In my case, I have a UHF flamethrower station 35 miles away South-East on RF22 (WNEM), that is 1 MEGA
-watt, and throws 874kW
's my way! It's located about 200 yards away from another tower broadcasting on RF46 (WBSF), that broadcasts a total power of only 70kW's, yet only throws 31
kW's my way. I have to use a Jan Jenca Jointenna device for RF46 with a dedicated HDB91x (91xg clone) aimed right at it
, to keep it from breaking up. If I don't, RF22 (WNEM) swamps it out.
Then at the opposite farthest end of my local station bearings, there's a station on RF16 (WSMH) pushing only 29.9kW's my way, located right next to a station on RF48 (WAQP) pushing 841kW's!
So, I have one HDB91x dedicated and aimed at RF46 with a Jan Jenca Jointenna, then I have a second
HDB91x aimed at the RF16 station (WSMH), which is my "all (UHF) channels EXCEPT channel RF46" antenna on that input of the Jointenna device. The combined output of the Jointenna goes into a Kitztech KT-200-COAX preamp, then into the UHF side of a Radio Shack UVSJ that's power-pass on the UHF side.
So, the two UHF HDB91x antenna's are aimed at the weakest stations
in my arc, yet on the "all (UHF) channels EXCEPT RF46" HDB91x, it not only gets full signal on my other weak station in my receivable arc (RF16), BUT, the other stations are still powerful enough that they come in fine with the antenna aimed as it is.
By the way, I also have a third High band VHF only antenna (AC Y10-7-13) aimed at and picking up RF12 (WJRT) which is my only VHF station. That goes into the VHF side of a UVSJ, and is not amplified at all.
