FM Dipole Antenna
Posted on April 26, 2008
I just added a dipole antenna outside of the mobile home mounted horizontaly on my deck. After some disappointing results on coverage, i could see i wasnt anywhere near 200 feet (range wise) with the antenna inside the mobile home.
Too much reflection and resistance caused by wiring and the aluminum siding. I wonder though, what kind of gain a dipole antenna would have if its cut for 95.7 mhz. I am using a 75ohm to 300ohm balun, the kind you get with a tv/fm antenna.
(Last I knew a dipole like this had little to no gain.)
The wire is 12 gauge automotive wire.
Cable is 75 ohm cable/tv coax.
And I feel it should have a attenuator inline as well just to be safe.
I hear no intereference on any other parts of the fm dial or in any other bands for that matter.
So how efficient will this be? By the way, the antenna is probably 5 feet off the ground.
Any input would be great.
