Scanner beam
« on: September 26, 2020, 1252 UTC »
These might make good scanner antennas (mount for vertical polarization).  In bulk, they are $12 each and have a Type F connector.

They remind me of the scanner beam that Grove sold many years ago.

Interesting. Nice potential for a group buy, but not sure how expensive re-shipping each antenna would be.

OTOH I guess you could install a bunch of them aimed in different directions, and select which one to use, as a reviewer did.

Looks like you can get two for $38 shipped https://www.mtcradio.com/buy-one-get-one-free-hdtv-outdoor-antenna-vhf-uhf-16-element-hi-gain-log-periodic-design/

The mounting hardware it comes with directly supports horizontal or vertical mounting, so nothing needs to be drilled.

Looks like they're also being sold on eBay for $25 each, shipped https://www.ebay.com/i/233400693902

I found that listing while trying to find some dimensional info on the antenna, which I still have not found.

Or, find a trashed TV antenna on a curb-side, junk store, or even a dumpster, and drill-out the holes in the boom to make it VERT, for next to nothing. Yeah... I'm that cheap, but this does work. Even some successful TV antenna MOD's for 6M, 2M, 222MHz, and 432MHz, Amateur Radio RX / TX.
I was asked, yet another weird question, of how I would like to be buried, when I finally bite the big one. The answer was actually pretty easy. Face-down, like a certain historical figure in the late 1980's, (I will not mention who, but some of you will get it, and that's enough.) Why??? It would be a burial that will satisfy everyone: (1) My enemies will say that it will show me where to go. (2) On the same point, I can have my enemies kiss my butt. (3) It will temporarily give someone a place to park a bicycle. See??? A WIN / WIN for everyone.

The dimensions (within an inch or so):

Boom length = 48 inches

Widest elements = 16 x 2 = 32 inches

Narrowest elements = 2 x 2 = 4 inches

Not looked into that antenna at all, but it is advertised as a Log Periodic which would be much different than a normal Yagi.

They are also offering buy one get one free https://www.mtcradio.com/buy-one-get-one-free-hdtv-outdoor-antenna-vhf-uhf-16-element-hi-gain-log-periodic-design/

Ordered a 'buy one get one free' for 25$ shipped via eBay. Have a few old TV rotators to play with.

What's the URL for the BOGOF for $25 shipped via eBay?  I see BOGOF on their site for $25.99 + $12 shipping, and one on eBay for $25 shipped.
