There is a 250 watt station about 40 miles from me, but its antenna is on top of a mountain. I can receive it from my car, with a stubby antenna they use these days, when driving into my garage, and a spot in front of my house. It is on a frequency of 92.5. Direction is 320 degrees. There is a much more powerful station about the same distance on 92.3 at 170 degrees. I ordered a 4 element FM yagi with a folded driven element, integrated 300 to 75 ohm balun. Lists Front to Back as 15DB. I was hoping that would null out the station on 92.3 but no such luck. Testing on the ground I can not tell the 92.5 station is there, but get interference from 92.3. Next step is to carry it up to the top of my 60' tower, and hope to catch a sweet spot. Just cannot figure out how my car radio can get it with a crap antenna, but a Marantz A/V receiver with a 4 element antenna cant. Any suggestions before I start climbing when it warms up?
