Thank you!

I bought the USB dongle for analyzing frequencies. So there are 4 sets of FM traps. 2 of the sets say hi "q" trap hi band. what frequency is this referring to? and the other 2 say hi "q" trap lo band/fm, Obviously these 2 are blocking fm, but what are they referring to when they say lo band...

Thanks for the recommendation. That would be something good as the channel would be operating at 515 mhz, or channel 21. Are there any filters that would just block 21, or is that really my only option. Worst case scenario I lose a couple stations between 19-23

The small tower is an old at&t long lines site, not used anymore now with cellular, 2-way radio and a couple of microwaves dishes https://www.long-lines.net/places-routes/maps/MW6610-E-inset4.jpg

WEDW is staying. They are channel sharing with others, including WZME, which is moving to another place. CT Public Television just got approval to remove their side mounted antenna, put a new antenna at the top. and upgrade their transmitter. Since the increased height of the antenna, and beam...

I think its a report by location. I did the report for my house and did another report right down the hill toward the end of my street and there is significantly less receivable channels, as well as the transmitter located close by, wedw the signal level changes from my house to the end of my...

So you basically there is 2 fm traps, which i assume help eliminate fm frequencies. then those go into the 4 sets of dials, which i assume you tune those dials to reject a certain fm frequency. If those reject fm how do I tune them? The fm channels I would be trying to block are 89.5, 91.1...

Sorry if some pictures are duplicated

I have just acquired what seems like a vhf/uhf/fm amplifier/distribution system for an apartment building. The antennas on the roof are long gone, but the box is still there. the equipment is very old, as it is probably original to the building. Are these things still usable? if so, how would I...
