I'm going to buy the RCA ant751 for 4 tvs, attic placement, 20 miles away, high vhf channels biggest concern, and a guy at an antenna company suggested both a preamplifier and a distribution amp but said if I only get one, the distribution amp is more important. Do you concur? If so, I'm thinking one of these two, any suggestions?
$37 but it seems I'd have to get a 4way splitter to go with it
Channel Master 3414 4 Outputs Distribution Amplifier
$33 and it has 4 outputs.
is more expensive for less outputs indicating a better amp? or is the channel master the obvious choice?
Also, if at all possible, putting your antenna outside on the roof will increase you signal strength, thus decreasing your chances of needing an amp. The ANT 751 is not a big antenna, it can even be wall mounted.
thanks for the advice. I think I'll do what you suggested and test it with a passive splitter first, but if I decide a distribution amp is needed, which of those two would you suggest?
Depends entirely on your physical setup. You can use the one with four outputs, if you have a place to "home-run" the cables from. You can use the single-output one some place convenient, then put a four-way splitter (or, even a two-way, feeding two other two-ways) where they will work out best.
Most all of those distribution amps are just a 15 dB amplifier, with or without built-in splitters. They make different versions (1 out, 2 out, 4 out or 8 out) just for convenience of the installer.

The only amp that worked for me in my mixed signal location (extremely strong and extremely weak signals from the same direction) is a discontinued model from Winegard that should be able to be found on e-bay; the DA-1018 (18db gain). There is also a DA-1036 (36 db gain), but it overloads easier due in part to the higher output.
