FM antenna for MR85
 

With all the talk about radios as of late, I convinced myself that I needed to have a tuner in my system. (thanks Dan for all the subliminal mind control about a system not being complete without a nice tuner). Anyhow, I am picking up a McIntosh MR85 next week and a was wondering if there is a recommendation for a indoor/outdoor antenna that I can get from amazon that would optimize FM reception ( I am now a Amazon Prime member so I need to make use of it). Suggestions would be great.

Ed... this is the only antenna you should buy. :ok:

Ed.......I agree with Ivan. The Magnum Dynalab ST-2 is a very good FM antenna. It can be used inside or outside. My ST-2 antenna feeds my MR88. I am very satisfied with its performance.

Ditto.

Thank you Ivan!

And, good move on the tuner. If you have even a couple of good stations that still pay attention to sq, it's worth it in my book.

Agree with the ST2, I use it indoor with excellent results.

If you want the same exact antenna without a MD sticker for less money look up Metz Communication. They're the OEM for that antenna.

Do you all think these Metz and Magnum antennas in the attic are going to be any better than an attic mounted Radio Shack antennae for a Mc TM-2 tuner card? I live in a suburb of Phoenix which is pretty much a flat urban area. Since this is the year of tweaking things, I am more than happy to swap antennas if it will improve FM performance. :music:

Yup, just do it! :yes:

I am going to differ with others posting here and say emphatically: Maybe. Or, maybe not.

There are just so many variables involved when you try to assess the best antenna for any task. Is your Radio Shack antenna a dedicated FM antenna, or is it also a TV antenna? If it's designed for TV, you'll want to make sure that it is also designed for the FM band, which is VHF and fits between channels 6 and 7. To prevent interference, some TV antennas deliberately filter out the FM band. Others provide an option to do that with a removable tab or trap on the antenna. You're already using the antenna for FM, so it's likely it was designed to be used for FM.

Then there's the question of your location. The closer you live to the transmitters, the greater the chance that something like the MD antenna will work for you. But there's no way an omni antenna such as the MD can have the gain that a dedicated, directional FM antenna can. So if you live out on the fringes of a station's reception area, it's very likely only a directional antenna will work best.

In addition to the gain of the antenna, another variable is the install itself. Generally, there is no substitute for height. FM reception is theoretically limited to line-of-sight between transmitter antenna and receiving antenna so the higher each of these is, the better your reception will be.

Then there's multipath. Whether it's caused by natural conditions such as hills and trees, or man-made conditions such as buildings and water towers, if this is a problem in your location, a directional antenna will outperform an omni every time. Note that multipath isn't always audibly obvious as such, but can sometimes be heard as just slight increased distortion.

I recall a friend who used to live just outside of NYC and who got horrible FM reception even after trying several different omni antennas. The problem was multipath. We replaced the omni with a high-gain, directional antenna. That fixed the multipath, but the increased gain overloaded his tuner input. But once we put an attenuator on the antanna feed - wow! He got super hi-fi reception.

As for directional antennas, a dedicated FM antenna will outperform a combo TV/FM antenna, all other things being equal. Unfortunately, dedicated directional FM antennas are increasingly rare; many major manufacturers such as Winegard and Channel Master no longer make them. But they are still available and needed by broadcasters for relays and translators, although those designed for commercial use (such as Kathrein/Scala) can get pricey.

Also important in any antenna install is the routing of the downlead and the choice of wire itself.

Again, there are so many variables with FM reception that it's really difficult to determine for sure what will work best in a given installation. Some trial-and-error is often needed for best results.

Curtis.......:goodpost:

I would add that if one uses a directional FM antenna you will also need to use a remote controlled rotor on the antenna mast so that you can point your antenna in the direction of the broadcast tower for highest gain or adjust the direction to help overcome multipath reflections. With a directional antenna there is no 'set and forget' unless the towers you wish to receive from are all located in one general area.

These two links should offers those interested in FM antennas (88 - 108MHz) plenty of reference reading:

cleeds and jdandy,
Thanks for the great info! I believe I put a directional FM antenna up there, and, other than the roof, I have pretty good line of sight and no reflection points...we are pretty flat here. Most stations' signals come from antennas on a central high point here...South Mountain. I will experiment and see what I get. Thanks again for the info.

Will have to see what works the best.I believe that the omni antenna that I ordered should work well for me. There are three major cities near me...west/north/east all of which broadcast FM.
Ed

Thanks, Dan! This is so true that it was an error of omission for me to have not mentioned it. Directional antennas often don't lend themselves to a casual scan up or down the dial for that reason.

As a workaround, I use a fixed directional antenna and an omni. They each have separate downleads to my tuner, which can switch between the two antenna inputs. Most of the stations I listen to are on one of two master antennas, each located on a Very Big Building in a fairly distant (60 miles) Very Big City, and each essentially in the exact same direction. It's in that direction that the directional antenna is oriented. The omni antenna picks up the few local suburban stations that I listen to and - because they are more local stations - the omni suffices. The omni also does a surprisingly good job with the distant stations. But, when I switch to the directional antenna, there is no comparison between the two.

Oh I am so, so jealous of your reception conditions!

Congratz on the McIntosh MR85. I picked one up from Ivan just a little bit ago. I enjoy the tuner and love the look in my rack.

I also was in antenna confusion. I seriously considered the st-2 that many have recommended. I end up with a Terk FM50; their top of the line FM only antenna. So far it appears to work fine for me laying on the window frame behind the shade. The problem is placement and especially in a brand new house we are having built. The antenna is more of a dilemma than the tuner.

So I decided to try one more... the Godar FM1A, that many on here have had and rated well. The idea here is that it can just sit on the tuner or rack, no muss no fuss, versus mounting and placement... if it works well then great... if not then the ST-2 will be the next try. I just don't want to have to mount something if I can get away with it... the antenna has been more difficult than picking out the McIntosh tuner :)...

Well the Godar FM1A works badly for me. Also, the ST-2 are sold out pretty much everywhere :(... but... with the help of a friend I have located a Metz and ordered it. Metz actually manufactures the ST-2 for Magnum Dynalab. Their model 288 should be exactly the same as the ST-2!

Randy.......I think once you get the Metz 288 connected to the McIntosh MR85 you will finally be satisfied. That 1/2 wave omnidirectional antenna provides 2.5 dB gain. You should be picking up stations all over the place. Hide it behind a curtain and you'll never know it's there.

That is what I am thinking also. I would have bought the MD, but no one has one. But one nice benefit, shipping and tax the Metz is still $45 less :D...

The MR85 sounds fantastic... just got to get the antenna to match it :)...

Hmmmm! This is getting me interested. I have a beautiful vintage Marantz Model 105B tuner gathering dust. Maybe it is time to put it into service.

Do it Douglass! :)

Randy...It should be a nice project. :thumbsup:

Well I have the MR85 all connected and it sounds great. The ST2 antenna works better than expected. I was
happy to see how many stations i was able to pick up. I'm glad I made the move to include a "radio" to my system.
Ed

Excellent Ed.... I to am glad to have added the MR85! Waiting for the ST-2 myself.... have tried several antennas and definitely know that it makes a difference.

Amazon just got some ST-2's, so I decided to get one since I have no confirmation that the company with the Metz actually has them in stock. If they both arrive I can return either one :)...

Well I confirmed that the Ham Radio Outlet did not have any Metz in any of their locations so I am very happy that I had ordered the ST-2 from Amazon when they got them back in stock!

The SR-2 arrived. Besides getting it out of the dam tube, installation is easy. I had to play around to find the best location. Laying on the windowsill worked fine for most stations, but the NPR stations would not come in at all.

Finally found best bet for now, clear taped the mounting bracket to the window with the whip up. After finding best spot seems to work very well. The Mc never sounded better.

I laughed with your comment about getting the antenna out of the tube. I spent more time opening that darn tube than I spent installing the antenna!!!!! I have access to the attic of my house so I was able to mount it inside the attic. The antenna is about 25 feet above ground level. I have been enjoying the FM stations a great deal. Happy I made the move.
Ed

Ed.......Congratulations on putting FM radio back into your system. It is a wonderful source component that many choose to ignore. Too bad for them. FM radio is entertaining, spontaneous, and just plain fun to go looking for new music and distant stations. Don't overlook the AM band on your MR85. Install that external RAA1 AM antenna up in the attic. There's a lot of cool stuff on AM, and at night you can pull in stations from all around the country. A sound system without a tuner is incomplete in my opinion.

Glad to hear the Magnum Dynalab ST-2 antenna is doing its job well. Installing it in the attic at that elevation definitely improves it's ability to receive signals. My ST-2 is mounted at 28 feet from the ground to the bottom of the antenna on a second story eave outside. Even in this rural north Florida location and acres of oak and pine all around my home, the ST-2 does an excellent job with my McIntosh MR88 tuner.

Honestly, I didn't give AM a second thought. I have NO idea what AM stations have to offer. But, It will not take much more than a half hour to set it up and give it a try. Heck, I may be pleasantly surprised.
Ed

Wow. I can't listen to it on the big rig, but AM 1690 here in Atlanta is awesome. They play everything from the waylin jennys, to Sam Cooke, to reading Shakespeare (and lots of other stuff), to great stand up comedy, routinely, all the time. If they just had an fm signal, it would be too good to believe.

This evening I found a Blues/Jazz show on a Santa Barbara station that I was not able to get before! It was full strength but a little static when in stereo. In mono it is crystal clear... turn on the spatial enhancement and it sounds fantastic. I also found out that the tuner remembers these settings for that station! Awesome!

Randy... very glad to know you are enjoying the MR85 :)

Thanks Ivan.... it is an excellent tuner... all I could possibly need!
