I tried this filter with my ATT U-Verse due to RFI on the TV from my ham station -- especially on 20m. Unfortunately, U-Verse is actually using HF spectrum to feed their TV box and so the filter did what it was designed to do, I swept the filter on my lab bench and it meets the specs, so I can't fault it and only fault my lousy understanding of how VDSL works (I didn't know at the time and assumed it worked like regular cable TV).

This filter exhibits very good pass-band and stop-band characteristics. At frequencies below 37 MHz it measures nearly 60 dB of attenuation. Above 51 MHz the loss appears to be under 1 dB. It is just what I need to protect my roof-mounted TV-antenna preamplifier from my HF ham radio transmitters. Being this filter is AC coupled, I expect that it will also provide substantial lightning protection for the preamplifier. It appears to be well designed and well constructed. If you need to attenuate low-frequency signals, this HPF will do the job.

If you have a vhf antenna and are anywhere near a ham radio or CB radio, I would try it.Should be half the price or 2x the function (FM trap, Ham/pager/GMRS, & LTE 600mhz filter!)Not happy stringing this with a dc block, power inserter, & LTE filter, but sadly the combos are more expensive.Still need a GMRS filter too.

i did everything and even went on Google.com and its said to cancel your service and install it again so i did, but it just made by signal worse. and i didn't even get any extra channels. I even think i have lost some channel so just don't wast your money on this

This work successfully to reduce digital OTA signal disruption from passing GPS-equipped vehicles or mobile-phone users. About year or two ago, I've noticed disruption is returning, and I surmise, frequencies on smartphones and GPS units have changed. I will seek out an upgrade. But, otherwise, no complaints on this handy little gadget.

Worked great. Cable Modem noise was no longer visible on the TV.
