I am looking for a signal combiner/splitter for FM/TV, a part that is getting harder to find. I found the MCM Electronics #33-350 that should do the job but I can't find any specs on it. Do you know...

Update

Looks bad. What elevation did you enter on the Fool report? I'd keep raising it and see when you get 1Edge or even LOS. This will give some idea of the difficulty. Are you behind a mountain? 48...

I want to run a test to see if the polarization makes a difference. Making that Bazooka antenna costs me about an hour of my time and a piece of coax so its not expensive and I am curious if it would...

Yeah, it was a shot in the dark tapping my ANT751 but it wasn't difficult. Previously I made a custom folded dipole optimized for 105.3 but it still had static. This was mounted indoors on the wall...
