External antenna as dish?
« on: February 11, 2012, 12:42:43 PM »

so I know you're not aloud to put an antenna on the rooph in the villages, unless its a dish. Is there any external Fm antenna dishes out there that I can hook a roter too?  maybe it wont be  as good as say the antenna guard, but maybe there's somethin that will at least be better then what I got as far as  6 foot telascoping wip..

Are there any external FM antenna dishes out there that I can mount on a rotorIt may not work as well as, say, the antenna guard, but maybe there's something that will at least be better then what I've got as far as 6-foot telescoping whips go.

I am now posting aircheck files and such on Youtube under https://youtube.com/user/oldradiotapes on an experimental basis.

When downloading any of these files, please use only the type 22 (720-P) option when available, as it provides the highest-fidelity audio (MP4/192k AAC).

By "FM antenna dish", what exactly, using proper grammar and spelling, do you mean? An old-style BUD connected to an analogue C/Ku-band receiver? Those aren't of much use these days, since almost everything "up there" that's free-to-air (or free-to-view) is in DVB or Digicipher 2 format.

If you'll recall, NTSC video was/in carried on satellites as FM signals instead of AM.

I'm lookin for something that I can run a coAx cable into a tuner such as the Yamaha T-85. I'd like the antenna to be able to be hooked into a roter. This way I can turn it in different directions to pull in stations from Tampa, Crystal River, Jacksonville. I don't think that those would be too far a  stretch for daytime listening. Perhaps  the night could pull in SE Georgia and Tallahassee too.
I figure it this way. I've been able to pull Tampa Jacksonville and Crystal River in the car when in a standstill with nulling out say WNDD to get WXCV etc, and with the 6  foot whip, I've been able to get Tallahassee  at night. I figure if I can do that with a car radio and boombox, that a dish could at least do that much if such a thing even exists.
I realize that I'd  have to  modify the T-85's filters to get the best reception for recording airchecks and defeat the stereo muting. I may just bring the one I have from PA next time here instead of gettin a new tuner and modding it. But before I bother with the new tuner I wanna be sure that I can get a dish (something that the villages would allow), before investing in a tuner  or bringing the one I already got here.

In addition,  a plus would be to be able to pull in stations from Daytona Beach, Gainesville, Lakeland  or stations such as WMUV (Brunswick, GA), WYRE ((Saint Augustine Beach) ,  or WAOA(Melbourne)
Maybe there might be a shot at pulling in the LP WIGT in Ocala but I don't think its powerful enough to make it this far out.

So to summarize I'm looking to pull in the following markets.
Crystal River, Tampa, Jacksonville, Lakeland, Daytona Beach, Gainesville, Saint Augustine Beach, and Melbourne.
Some of that may be a bit of a stretch, but maybe not.

Thanks for all your help .

It sounds like you're living in a home under an (ugh) HOA, or if the home owner doesn't want an FM antenna on top of the house. If that's the case then an FM yagi or dipole may be better off in an attic. I don't think a dish would work out very well in receiving FM (88-108) signal.

what is the difference between an FM yagi or dipole? is that different then the antennaguard that i have up north?
 The Villages is a very strict place. They don't let you do stuff like that, put things on your lawn etc. as I'm blind i wouldn't know this per say but I've been told this area is very emaculit looking which is nice visually, but it doesn't work well for antenna's.
If I were to put one of these in my attic could I still rotate it? could it be  directional? I'd have to measure the antenna and attic for size which makes sense, but past that are there any other considerations?

John, an FM Yagi would be small enough to fit in most attics I would think and mounting it on a pole with a rotor would be possible as well.  You would only need 3-4 feet vertical.  Before you begin though you should ascertain if your attic is lined with some sort of metal foil (used for heat isolation) as that may attenuate the signal significantly. 

Here is a good definition of an FM Yagi:

Attenuation is a loss of signal usually by objects the signal has trouble penetrating.
