Pertinent Information:
Zip code 34135.. (only interested in digital signals)
100' RG6 from antenna to house connection.....(otherwise I'm in the hi-power lines)
3 TVs on cable loop through house (figure approx 100' more of RG6 added for the loops inside the house)
Two Dish VIP211 receivers.
Max distance to transmitter towers 35 miles.
No more than an 5 degree spread between transmitters

All digital channels are UHF except for CBS (channel 11.1 frequency assignment 9)

Will mount outside on mast approx 15 feet off ground...no trees or building obstructions...will shoot over all the house in the neighborhood.

Antenna choices are:

Radio Shack VU 90XR
Channel Master 3016
Channel Master 3018

Because I can return them if they don't work :eureka

Currently using a small amplified (10-12db) HDTVo Audiovox antenna mounted to dish mast, Getting FOX, ABC, NBC in the high 80's to low 90's- NO CBS at all (lost CBS when I swapped out 811's for VIP211's)- PBS and Ind located with receiver scan but low signal strength mid to high 50's...unwatchable.
:(

I'm wondering if the RS 90XR or the CM 3018 are big enough to grab signals with out pre-amp? Figuring the 3016 will need a pre-amp. :confused:

Suggestions..recommendations....pre-amp choices? Antenna selections. I only want to do this once.....:)
