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".

I purchased the LTE Filter hoping it would help resolve the issue I was having with my HDHomeRun freezing for a few seconds but it made no difference. Mine is placed just before the amp. (Removing the amp did not help either) I will post the issue else where but thought I would post my results here hoping it might help someone in the future. The filter is nicely made and I wish it helped my issue.. I left it on as it does not seem to affect my signal quality which normally runs at 100%.

When looking at LTE filters be sure to look for 608MHz pass / 618MHz reject – if the pass band is below 608MHz it will block the higher TV frequencies. If the pass band is above 608MHz it will not block the new “600MHz” LTE band that starts at 618MHz.

Regarding a Televes 149883 antenna with integrated amp and Silicon Dust LPF-608M 5G LTE filter:
Since this antenna output and amplifier are one and the same, which direction should the SD LTE filter be inserted?
Can the male end be coupled directly to the amplified antenna output, or do I need to use a short coax between the 2 components?
I am confused because the filter is clearly labeled as being directional and how to insert it in a "normal" configuration with a separate amp.
Is the filter truly directional?
My intention is to eliminate as many components / points of failure as possible in my installation.

Install the filter on whatever is directly downstream from the amplified antenna + cable. Direction will be right and no adapters needed.
