Opinions on narrowband FM Radio antenna?
I know this is really an OTA TV forum, but you guys know your stuff better and have more experience building than anyone...
My great old Winegard 6065 FM antenna got torn up in a freak storm a couple of weeks ago and I'd like to take a shot at building something to replace it. Part of my motivation is that the only stations I really care about happen to be from 103.3 to 107.7... Obviously a small part of the band, which helps tremendously. I don't think I'll need multiple driven elements, and it's also nice that the antenna can and will be smaller (or at least not as wide) when designed for the higher frequencies.
What would you guys recommend for a medium-sized yagi for my situation? The 107.7 is the more distant station... The 103.3 is 95 or so miles away but actually comes in very well with just an old Radioshack/Antennacraft FM-6, so I'm thinking I'd rather tilt things toward the higher end of the band. I've read Brian Beezley's site and seen his narrowband yagi designed for the low end of the band, and I could simply scale it for the higher end of the band, but it's larger than I want to build.
I was thinking of simply running a model for a 107.7 yagi but with a 103.3-sized reflector -- sort of the design of the Winegard YA1713. Or do you think a yagi designed for 107.7 or even right in between be better? I just know in looking at TV yagis, the gain drops off precipitously once past the peak frequency.
Thanks, would be interested in any thoughts you guys would have.
