I had a new HDTV show up for the shop todsy. I'm heading to Wally World looking an antenna for it tonight, any advice?

good info here also.
The picture quality for me is as good as cable TV. My stations are about 15 miles away. No rain fade, no signal loss ever. So simple, and good quality.
Notgrownup, you're not far from me. I'm just past Lizzie, next road on the left coming from Snow Hill. Stop by sometime.I had one of them huge ones hung upside flown in my attic, I got channels from Raleigh and Wilmington, I live in Snow Hill so not too far....the better Hdtv ones seem to work ok also...we had one also but gave it to the kids gorgeous the lake trailer.
How good of a picture quality can you realistically expect if you have a good signal? Seems like a awful lot of data to be transferred if the image is in HD.

The passive return is probably so you can hook up a cable modem and have its uplink/ backhaul make it through the amp and go to the cable company.
I would get a "decent" amp... 12 to 20 dB is plenty... and hook it up "nearish" to the receiving antenna so it doesn't amplify line noise. After that, it doesn't much matter if you tap one port and put splitters on or if you have each output go off to a different room. Depends on how your house is pre-wired.
I've got a question relating to this. Right now I am splitting my antenna signal to 4 TV's using a passive splitter that reduces the signal by -3.5db and -7db. Most of the time this works OK, but the signal strength isn't the best especially in the rooms with the longest RG6 runs. It also causes occasional signal problems for my TV card (on my HTPC) depending on the weather.
I want to improve the signal strength and distribute the antenna signal to 8 locations. I think I need to buy an 8-port distribution amplifier to send this signal to the TV's, however my head hurts after trying to figure out what to get on Amazon. The reviews complicate things and it's hard to tell if it's user error or the wrong product. Anyway... I'm looking at this specific unit: 8-Port Bi-Directional Cable TV HDTV Amplifier Splitter Signal Booster with Passive Return - http://amzn.com/B000WDR94U. Is this what you guys would recommend?
I have that amp.....works fine.
As for your splitter....actually...it's 7 DB on all ports. Signal comes in and is spit to more splitters...so those splitters are now getting 1/2 the signal strength (3db drop is half power). Those spitters are then feeding your TV's....and since each one drops it another 3 db....you end up with 1/4th the power of your original signal....toss in a less than perfect connection...bad coax, etc. Yea....rough signal.
For those not up on electronic terms, VHF is basically the old analog channels between 2-13 (in VHF 2 different bands 2-6 and 7-13). Most, but not all, digital broadcast are in the frequency that were analog 52-69. (There is some discussion by the FCC to make that the ONLY frequencies available in the future.)Just so it's understood....there is no such thing as an HD antenna.....or digital antenna.
If you have an old antenna from 40 years ago....it should work....not much of the vhf section is used as most of the HD stuff got pushed into the UHF range....hence, you can get by with a smaller antenna.

Designing and building an antenna for a smaller range of frequencies is easier and cheaper.
Most of the DIY designs on the Web/YouTube actually do work !
