Question Installing Omnidirectional FM Antenna

Hello All,

I was looking to install an fm antenna on top of a hill behind my house. The distance away from my house is about 50ft and the antenna will be at least 10ft off the ground. A few basic questions seeing how I've never done this before. First of all is this application doable? Also if I can do this is the cable used to bring the fm signal from the antenna to the receiver rg6 coax or standard antenna wire? Does anyone have any recommendations as far as an antenna and/or optional or reqired equipment (not really looking for HD but will take it)? Any information will be greatly appreciated and thank you in advance.

Yes, it is doable. Google omnidirectional fm antennas. Winegard is a good brand. You will lose some of the signal in the coax but using a low loss coax should work. You mention HD. Are you referring to HD TV?
FM broadcasts at roughly 88 - 108 Mhz while most (not all) HD TV is up in the 300 Mhz range.

No, dont need the TV signal, only FM. Besides the antenna, mounting equipment and coax is there any other equipment I will need or do I just connect the coax from the antenna to the radio reciever?

You might consider a marine antenna. The 8-footers are high gain and omni. Shakespeare website.

Just make sure all of the connections are watertight.

Adding a lightning arrester may be a good idea.

What is the difference between a marine antenna and an omnidirectional antenna?

The vertical marine antenna Rick suggested is omnidirectional. It is designed for exposure to harsh weather and may be a good choice for your application.

A lightning arrestor isn't generally used on marine antennas. They are fiberglass and non-conductive. In fact, I'm wondering if it will affect the performance. Unlike car antennas that use the metal from the car as a ground plane, a marine antenna is self-contained.

If you're mounting it atop a metal tower or mast, make sure the mast is grounded.

Great....I will be mounting it on a metal tower....By any chance does anyone know how deep a rod should be in the ground to create a good ground? Also does anyone have a model # of a good Winegard vertical FM marine antenna?

I don't know if Winegard makes one. I do know that Shakespeare is ubiquitous. I have two of the 8-footers on my boat. The antenna is about $35 and the mount is another $30.
