Where is WMHX? According to the FCC database, that is not a valid TV callsign.

WGAL, WGCB, and WPMT are all to the south of my location about 8 miles, and my UHF antenna is pointed to the east. I get both of these currently around 95-100% and both come in approx. 90° to the antenna's side. At 30 db, I don't get overload currently. An FM trap may hurt since the VHF station I am trying to receive is channel 6.

The Antennacraft Y5-2-6 won't fit in my attic b/w the trusses; which is why I plan on on making a simple dipole.

Is the channel 6 Jointenna a combiner that works w/ a ch. 6 tuned antenna and another antenna not tuned to channel 6; the Jointenna essentially prevents the 2nd antenna from tuning ch. 6 so that the other antenna (tuned to ch. 6) can do it's thing? Essentially an input highly notched @ 85 MHz (+/- 3 MHz) and another input w/ a 85 MHz bandpass filter with a 6 MHz bandwidth?

I'd only use one pre-amp in the line. I have 1 TV hooked up to this antenna but 1 splitter (TV and DVR). The total length of RG-6 is about 40' b/w TV and antenna.
