After seeing your real TV Fool report it is apparent that you need more than a simple UHF dipole. I'd suggest a DB4 type antenna mounted as much in the clear as possible and hope the trees don't do...

I'm saying that except for channel 3, it's not significantly different from what you've been using. It's not possible for anyone to predict how any particular antenna setup will work with 100%...

I think you should go ahead and do what you want and see what happens. I'm not on board with it for several reasons that I've already given. I've observed that people tend to take the advice from...

We need to see the TV Fool report for your exact location. The generic report shows all your stations to be strong, LOS and close by. This is as easy as it gets and there should be no missing...

Your stations are all very strong and only 10 miles away. This is about as easy as it gets. A simple RCA ANT751 mounted outside pointed at 112 degrees will get all your stations. Do not use a...

We don't know yet but after the repack there may be more low VHF stations. We just don't know where. That should be known by mid April when the FCC announces the auction results.

Alright.... What you've shown is that you can use any old piece of wire as an antenna and if the signals are strong enough you can receive them. :)

Your homemade antenna is poor on high VHF (WSET)...

I suspect there won't be much in the way of LP's sharing/leasing on a full power station. LP's could get together and share a transmitter. We have a couple of LP's here with just one stream and one...

This is the first I've heard of LPTV being able to channel share with full power or other LPTV stations. It's possible that many LPTV stations could remain on the air with channel sharing. Good news...

I'll be surprised if KBSV moves off 15. They have a special situation, very low power and a location blocked to the Bay Area so that there's no chance of land mobile interference. I'm expecting KMMW...

How is this going to work? Does a full power station have to complain about interference before the LPTV must go off or is an interference analysis done for every LP station to see if they'll cause...

Can you wait until mid April? By that time the FCC will have published what's happening to all the stations and you'll know for sure if you need low VHF.

Hi Keith,

You may very well be right but I don't think there'll be a full power station in Walnut Grove on 8. KSBW is really strong out here. KBTV analog used to be on 8 from Downtown Sacramento...

I suspect that many LPTV stations will be able to find a place to go after the repack is done. They may have to change antenna patterns to avoid interference.

The KGO translator will probably be...

Thanks Ron. That's the table I hadn't found. So 15 and 18 are also out in the Bay Area because they're adjacent to 16 & 17 and not >176KM from the city itself. So that means channel 18 may go unused...
