I plan to order LTE filter which will block above 608 MHz.
Place filter after antennas and before RCA mast amp.
Will report back after experiment.
Thank you for the new report.

Good idea to try the filter. If you order the Channel Master 3201 filter, make sure you get the NEW 600 MHz filter that says Pass 5-608 MHz Block 609-3000 MHz. They tweaked the 600 filter to reduce the loss to channel 36.

You can see the cellular signals with an SDR:

A less expensive SDR ($30), the RTL-SDR.COM V3, can be used with free DIY Scanner software from GitHub. The scan is not real-time; you have to wait until the scan has completed before you see it.
