I must have missed that when reading instructions ;)

My review: I just received and installed the LTE filter on my antenna.
The channels that had 100% signal level and 80% quality now have 100% level and 95-98% quality, Pixelization doesn't happen anymore, only a couple of seconds after switching to that channel.
I am "seeing" also a few extra stations that are farther way, and were not visible in scans before. Their levels are too small for usage, but IMO, they show that the first stage is not overloaded anymore.

All in all a good result.

Unless running an amplifier at the antenna. The filter should go upstream of the amp so that the amp doesn't get over driven.

The LTE filter being a passive device can actually be inserted in either direction, thus eliminating need for gender bending, can it not?
Experimented with reversed direction insertion with CM LTE filter and it seems to work the same in either direction.

UPDATE:
Actually think I was connecting directly to the antenna (female connection), then directly to the amp. So no coax until after the amp.

  1. a piece of coax with 2 RF connectors on the From Antenna end

  2. gended bender on To TV/Amplifier end

Why aren't both ends female or am I missing something?
If intent on gender bending instead of just reversing the LTE filter. An inline f-type-dual-male-inline-coupler may be more desirable than patch cable.

You won't overdrive a modern amplifier with the antenna signal. Otherwise all the cellphones would be "overdriven".
I installed mine at the output of the antenna amp and there are no issues.

What do you mean reversing? I don't think there will be any filtering if you do that.

I mean exactly that. Reversing. Why would you think there would be no filtering? It is a passive device.
The CM LTE filter seems to work just as well in either direction. I'd suspect the SD LTE filter is nearly identical.

1) The filter does not require any adapters. You attach it to the RF input of your device/splitter/amplifier and attach your existing cable to the filter.

2) The filter should be connected in this direction only - attach it to the RF input of your device/splitter/amplifier.

On what do you base this assertion?

On the base that that same chips, used in cellphones don't get "overloaded".
