Location: Seal Beach, which is right next to Long Beach (90740).
My home is about 20 feet down from the homes behind me.
I can only get 2,4,5 vis a 4228 antenna. 7 almost comes in, but then the HD-TiVO box say's no signal. I have pretty long runs of from the antenna.

I was wondering if I should try an pre-amp, and which one is recommended and where could I get one.
Or should I look into a directional antenna? antennaweb say's the distance is only 32 miles.

And could someone explain what the colors mean on antennaweb and how I'm suppose to pick an antenna based on the color?

Here is your antennaweb results. Many channel at 348 degrees and I would guess they are at the same tower farm based on mileage to the tower.

I would try a Winegard HDP-269 preamp. Additionally try to get as much height as possible with your antenna

All your digital stations are UHF and in the same direction, no need for a multi directional antenna...

Aus, I believe your best bet is to get your antenna a bit higher. It doesn't take much of a location or height adjustment to make a difference sometimes. You have one of the best antennas, so don't believe that is your issue. If your cable run to your TV or STB is more than about 50ft, then I would use a preamp. The Channel Master 7775 (UHF Only) or 7777 (VHF/UHF) preamps are pretty much the standard and I use them myself. I used to live out in Simi Valley and could pickup all of the LA stations from behind the Santa Suzanna's with a 4228 and 7775 from about 40 miles or so from Mt. Wilson. Try moving the physical location of the antenna a foot or so at a time along with getting it higher, possibly also slightly tilting it up. Any or all of these should give you some change in reception, hopefully better! Bob

Thanks for the feeback guys. I think the house behind me is blocking my signal, but why some channels and not others?

Also, where's a good place to get these pre-amp? THanks again.

Rick, thanks for that info. The channels I really want are 7.1(ABC) and 11.1 (Fox) and they're both yellow. I get 2.1, 4.1, and 5.1 OK.

What if my runs are a little more than 100 ft since it goes from the ceiling to the "can" and then to the TV's. Is the HDP269 still the one to get? How do you get "signal overload?"

Are you on the slope or at the foot of a steep hill or bluff that drops down to sea level? If so, I can easily imagine that the earth may be seriously impeding your line of sight. That kind of location is effectively in a deep "shadow" for TV signals. Any signals you're getting would have to diffract around the top of the hill. Maybe aiming the antenna upward towards the top of the hill would help in this case.

I'm definitely on the bottom half of our complex with a row of houses above us. We're not at sea level, but this was one concern I had when getting this house. I'll try the tilting of the antenna up a little with a pre-amp. Unfortuantely, raising it much more would draw more attention and the damn home owner's association may give me trouble.

Your HOA can't legally stop you from putting up an antenna, FCC law prevents them from doing so.

Thanks for the link. I'm not sure how this HOA will be, but the last one were pretty worthless and enforced rules randomly.

I'll second the recommendation for a preamp- I'm 27 miles from Mt. Wilson, and the CM7777 is the difference between an intermitten signal and perfect reception. And this is with a 4228 mounted only 10' off the ground without LOS.

Do you have to plug in these pre-amps to an outlet?

The pre-amps come in two sections. One is the amplifier which gets mounted outside close to the antenna and the other piece is the power supply. The power supply is intended to be placed indoors close to the receiver and plugs into an outlet. The two sections are connected by a single coax cable used to send the signal down from the amplifier and DC power back up to it from the power supply.

Got it. Thanks. I just didn't want to have to run a power wire up to the antenna. If it's all in the coax, that's easy to do.

Got the Winegard installed and it works perfectly on my TV's close to the antenna and pretty far from the antenna.

Thanks Rick for the suggestion.
