Update 26 Nov

Got one of these:

https://www.princessauto.com/en/search?Dy=1&Nty=1&Ntt=outdoor+HDTV+antenna

Can I do without the big "net" and the long VHF dipoles and still get OTA digital TV with the shorter UHF dipoles? I want to do without the "net" to reduce wind problems.

Thanks.

(The "net" as they call it seems to be a reflector like with WW2 British gunnery radars that had Yagis poking out of them.)

Since most digital TV stations have been moved to the UHF spectrum, and assuming you are not too distant from stations, that antenna should work well.

Depends on where the wires are attached, and which parts are actually active elements. I am not an antenna man, but many times the short dipoles and not electrically active, and are only directors.

Yes, but can I do without the "net"?

BTW this antenna has a neat feature, which is why I got it. It rotates with the power for that also coming up the coax along with the usual amplification power.

There is the long dipole for VHF and a shorter dipole for UHF close to the mast, and then farther out from the UHF dipole there are five shorter "directing bars"

The antenna in question will work without the net (reflector) but not as well as with it. I'd say assemble it with the net as they are very light and don't have much wind resistance. I have two similar OAT antennas with reflectors. One for use with my camper and one on top of the garage on a 10' pole. Been up there for past 3 years without wind problems.

"Some assembly required" to say the least. So there are wires to the big V dipole and other set of flat metal ribbon sort of "wires" to the U dipole. I guess that makes them active, as stated above. Seems like I can do without the V dipole if I want to, with the U one having its own "wires".

The net is porous, so might be ok in the wind--we'll see!

Have to try it out for the next episode in this saga.

Pardon my misunderstanding....I have been in the industry many decades and did not know to what you were referring when you said "net". That is apparently a reflector for mainly the UHF part of the antenna.....and yes, removing it will degrade the gain of the antenna. The long element is for VHF.....and likely not needed for almost everywhere. I would not drive an RV with any of this antenna up, so don't understand why you want to remove part of it.

Good luck w/ any part of that antenna. They are very fragile very cheaply made, mine won't even rotate when any wind is blowing. And in most cases, a batwing will out perform it.
