Hey guys, I am a newbie and I just installed my HD antenna. I kinda followed a few friends who had some luck with a brand they bought but I purchased one now and I am not so lucky.

Masically I purchased a MAX Digital outdoor antenna. It is approx 9 feet up on the side of my bungalow and cant get much higher right now. I can get almost all HD canadian channels except SUN but I cant get ANY US channels at all!!

Here are some specifics about my setup:

Antenna height: 9 Feet
Cable Length: 60 feet ( I know its long but I have a booster as well)
TV: Panasonic G20 and a Sharp Aquos
Anntenna mounted on J-Mount
Cable used: high quality RG6

I only get 11 channels and I am wondering if its just the height that is causing me to lose the US channels. maybe it is also the brand antenna I have used as well?

Any feedback is appreciated and if I missed anything please let me know.

Thanks

LOL I should also add my location huh.

I am near bathurst and 401 area...I figure with people getting US stations from Markham that I would have no issues getting it from where I am.

Anyway thanks for looking.

Most if not all of us are using a mast mounted pre-amp with at least 20 dB of gain, otherwise, no USA channels.

Also, if getting a pre-amp, make sure it can handle VHF frequencies also, otherwise no chennal 9, chn 9 does come in on UHF antenna only up here in Richmond Hill.

Other issue, are you blocked due south by high rises (Line of sight)?

Ah...ok well looks like that is my issue. The Antenna I have says 14db gain.

I dont have any blockages as about 80% of my southern view is clear but theres a massive tree to the left of it.

When you mention pre-amp...do you mean the amplified splitter where I plug the cable in?

Sorry for the dumb question.

From your list of items making up the system, antenna, co-ax and 2 TV's, you did not mention a splitter.

If this is a passive splitter, leave it in place (a 2-way splitter has min. 4 dB loss), if it is active amplified splitter, the gain of these is not enough normally.

An antenna pre-amp has 20 to 26 dB of gain, is mounted within 3 feet of antenna and has power supply indoors. If you use it with a passive splitter, the power inserter HAS to be after the splitter on the antenna side of the co-ax feed, NOT between splitter and TV's.

Google for amps, Wintronic has some and so do others, make sure it has both VHF & UHF rf gain, otherwise you will loss chn 9.

Basic system layouts from outside to inside.

Good high gain antenna, short co-ax (max 3 ft) to mast mounted pre-amp, good co-ax run to indoors (not more than 60 ft), add power inserter for pre-amp, add short co-ax to passive 2-way splitter, then short co-ax run to the 2 TV's.

Try to avoid amplified splitters for anything less than 3 tv's. More than that a very good cable amp/splitter with overall 0 dB loss should be used.

Good luck

What exactly is this "MAX Digital outdoor antenna"? I can't seem to find it online. UHF antennas range from a coat hanger to an 8-foot parabolic dish (always wanted one of those), and as always... the bigger the better!
