For what it's worth, I have some fairly strong signals, and I am using a Kitztech KT-200-Coax preamp, and it doesn't overload with an HDB91x antenna (91xg clone, and frequently on sale for $34.99 at SolidSignal. Sign up for their daily deals). My CM-7777 new model version preamp DID overload with the same setup, and stopped me from receiving any UHF channels, with the exception of the very strongest one.

Here's what I would do in your location:

I'd buy this antenna for VHF: http://www.mcmelectronics.com/produc...ductid=30-2475
I'd buy this antenna for UHF: http://www.solidsignal.com/pview.asp?p=HDB91X
I'd then buy this preamp if you need one: KT-200-COAX (right-hand bottom of this page: http://www.kitztech.com/

You then need to buy a UVSJ to connect the two antennas that is power-pass on the UHF side, such as the Radio Shack model. I use this one: http://www.ebay.com/itm/RADIOSHACK-V...UAAOSwYHxWGE1o

FM Trap: http://www.mcmelectronics.com/produc...-FM-88-/33-341

You aim the Stellar Labs VHF antenna at 75 degrees magnetic for your strong VHF channels. KUFM is the only one that's off that bearing, BUT, it's strong enough that aiming away from it is a good thing, and probably will still work to get all. If not, you can try splitting the difference and aim in-between 75 and 125 degrees.

You then aim the HDB91x directly at KTMF at 75 degrees, and put the preamp between the UHF antenna and UVSJ. So, the preamp will only be on the UHF side. If you install and FM trap on this side, the FM Trap needs to be installed between the preamp and the antenna. So, antenna ---> FM Trap ----> preamp ---> UVSJ

The VHF antenna goes into another FM trap, and then the UVSJ on the VHF side, and won't be amplified at all.

The antennas need to be mounted about 3ft apart on the mast, so you may need a slightly longer mast.

I basically have this exact same setup (just a different VHF antenna) and it works perfectly for me. Mine is just reversed in the fact that I only have a single VHF channel, and all the rest are UHF.
