Your installers and his boss are full of it.
I'm down in Albany, Oregon (below Salem), about 70 miles from the Portland stations, and I'm pulling in Portland HDTV
with a Channel Master VHF/UHF antenna. I have the Channel Master 3671http://www.channelmaster.com/pages/c1.htm
Which is similar to yours, but bigger since I'm much further away.
I can verify that I can pull in the OPB station from Corvallis (10 miles away) with NO ANTENNA!. That is,
just a strip of coax cable plugged into my HDTV receiver and I can get the Corvallis station.
It is not your antenna per se.
However, I'm not sure what the 'hills' you refer to may be doing. If they are small, I wouldn't think
it would be a problem.
Also, you have a directional antenna, so be sure you play around with pointing the antenna
in different directions.
At 5 miles away, you should be able to get HDTV with a pair of rabbit ears!
There is no need for any such thing as a "High Definition" antenna. The signals are broadcast
on the UHF spectrum, and a standard UHF antenna should work fine.
Call their bluff.

I have a Channel Master 3016 VHF/UHF Antenna. I am 5 miles from the towers but I can't actually see the towers from my house due to some small rolling hills. ... I just temporarily attached it to my deck on the second floor of my house.
The installers say it's my antenna. They told their boss exactly what antenna I had and he said 'good luck getting HD on that antenna' that I needed a 'High Definition antenna', one of those 'hamburger grill' antennas. Which I eventually deciphered as a double bow tie, and I've read that those are good, but I want the VHF as well and I've read that a number of people have had success with the 3016. So they say it's my antenna, I say it's the 8vsb or receiver. Well they don't have another 8vsb or 6000 with them, so I should try the 'hamburger grill' and if that don't work then they will come back out and swap the hardware. I think that is a bunch of malarky.
