New 9 Element FM antenna

[n8fnr]

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

Well known FM antenna expert Brian K6STI says it likely is not great. That's too bad..

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.

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.

How do these two antenna compare, is one more preferred for pulling GB stations and other Wisconsin stations?

I’m about half a mile from Lake Michigan in manistee. Wixx occasional fades out with current (8 element?) antennacraft yagi (WAPL stays in better). I can pull in 104.5 WSNX and 107.9MUS very weak but fades too. I don’t expect much improvement from mi based stations.
