Sky Blue has released a 9 element antenna for FM. Supposed to be a copy of the Channel Master Stereo Probe 9. Looks interesting.

Re: New 9 Element FM antenna
Well known FM antenna expert Brian K6STI says it likely is not great. That's too bad..

Re: New 9 Element FM antenna
SUCH a long boom would be very touchy aiming for a weak one !
The biggest Yagi i used on 3M was only 5 elements.

Hi Z. You live between most of the high power city FM antennas !
Maybe we can chat on 6M , I check the low end of the band when I hear E-skip reports. usually sit on 50.090 kHz.

Re: New 9 Element FM antenna
I had an Antennacraft FM-10 on a rotator on top of a two story house, with an Alliance T-45 Rotator, on a 3 foot tripod.
In Genesee County, I could quite easily put WRIF 101.1 in a side null with the rotator and get WIXX 101.1 Green Bay, and WBRN-FM 100.9 Big Rapids quite regularly. I word rock it back and forth a couple times. The length of the boom is 117 inches, with a short double boom.

Slight differences between the Channel Master and Blue Sky 9 Element Antennas. Phasing lines and director attachment and connection to boom are different. Channel Master picture from k6sti site. Blue Sky antenna picture from specifications.
