Fascinating read –well done!

tripelo,

It’s obvious that you put a lot of work into this professional caliber test report. I wish more people would take the time to pictorially depict their test setups like you do. Clear, concise & helps answer questions generated while reading your reports.

I’d be really pleased if I had your signal environment. My strongest signal of interest is ABC, channel 7 @-87.0 & 2-edge to boot. Box Springs Mtn. 3.5 miles out my back door and in-line with my LA stations is home to numerous communication towers, a channel 26 PBS TV station, several FM broadcast stations, a 2-Meter repeater that just booms in on my TV antennas plus I also pickup four NOAA weather channels with my LA array.

One of the items I found to eliminate some of the unknowns in my testing was the inline Channel Plus LPF-750 Low-Pass Filter. It’s basically a 0 to 750 MHz band pass filter I use to remove the cellular signals emanating off Box Springs Mtn.

The only amplifier that I’m aware of that filters that portion of the spectrum is the new Antennas Direct Juice. ADTech did an excellent write-up on that amp here:

Looking forward to your follow-on.
