Thanks!
Not sure if your old enough to remember Heathkit Televisions, but I still recall building a Television Kit with my Dad back in the 70's - it was 'super high tech' for it's day with such advanced features as color, a wireless remote channel changer and get this... a built in rotor control so when you changed stations the rotor who move to a preset position (I still can't get my HTPC to do that).
Quick questions - When mounting on a tower is it still best to keep the preamp and combiner where it will be protected from the weather or since the result would be that you would end up with a 40' run of cable between the antenna and the combiner / preamp is it better to mount it up the tower?
BTW when searching for pricing and a supplier on the tower you mentioned came upon the used 490' freestanding tower in the picture for sale (and it is currently in Ohio) used for only twice what the Rohn folding would cost.
Put a Wade PB-82-BB Twin 8' Parabolic at the top pointed in the right direction with it's 25 dB gain and should be able to pull in those US stations real good.
