Mediocre reception so far.
Here's the initial test. This is the RTL SDR Spectrum analyzer, with the new array pointing at Milwaukee and RF 8.
Here is a scan comparing my one operational 30 - 2470 versus the two paired up and extended Blue is the pair and green a single. Quite disappointing:
The funny thing is some UHF channels come in perfectly. Even from the opposite direction;
Surprisingly, I pick up a few Chicago UHF stations quite strong with the antenna pointed in the exact opposite direction. Keeping in mind this is a VHF antenna(s)
UHF CH 7:
UHF CH 9:
So, why is the signal just mediocre?
It's possible the sagging in the antennas is causing the directors to be out of alignment with the dipole?
