Well Ive ordered a HDP-269, a 4 way splitter and a Winegard CC 7870 2-Way TV Antenna Joiner Coupler. I originally bought a 5-1000mhz splitter/combiner, but people at solid signal told me to by this (CC 7870). I hope I did the right thing, did I?

One other question, Tigerbangs, I know you kinda said to put the preamp after the signals are combined. The preamp averages 12db gain, and the coupler has a 3.5db loss. Does that mean having one preamp, each antenna gets 6db, minus 3.5db (coupler), minus 7.5 db (4-way splitter)? Plus my coax runs. I hope (but if not I will buy another) one pre amp will be enough and put it after the antennas are combined, close to the antennas. Put I know in the past Dave may have suggested two preamps, one for each antenna. Since right now I have one preamp, I'm not making up for the 3.5db loss of the coupler, since I have to put the preamp after the coupler?
So is one preamp ok? Or do I need two? Or should I put the preamp before the coupler for the HBU33? I would play around with this if it was easily accessible, but as you know, it wont be.

I have about ten feet of coax ready for each antenna, then I combine them, and run 1' of coax to the preamp. I made 10' runs because It will allow me to access the preamp, and coupler if I ever have to, and puts them at a safe, accessible height on the tower, but not the safest where I would want to be climbing it all the time.

One other thing, could I utilize my phillips 18db signal amplifier anywhere in my system? I bought it awhile ago, and I'd hate to have it go to waste. My MANT 940 is going to waste, so Id hate to be out $60 bucks total on top of what I've recently bought.

Last thing... How crucial is it to get the coax insulation close to the very end of the f connector? I can get it pretty close most of the time, but not always (1/8" off sometimes). I have a professional crimper, so thats good, but I use channel locks to push the f connector onto the end of the coax, and the end of the coax doesnt always go flush with the end of the f connector (I think you know what I'm trying to explain). Will this cause significant signal loss? Hope not...

Thanks for everything, my annoyingness will cease soon, next week the antennas are getting put up...trying to get everything set up exactly how it should be.
