    Deployed at a repeater site- lots of RF- looking for filtering options. The radios are fairly deaf as a result of the rf on site. Ubiquity dish and sector antennas mostly.
    Thx

    Is your 5GHz running through dishes, or patch antenna. If patch, does it really need the wide pattern? Maybe a dish would not pick up the sidelobe junk?

    Thx for info on pipe cap filters.
    There are multiple nodes at the repeater site. None of them are mine but various repeater groups and members. There is at least one sector that is facing away the rest of the site and towards the valley below where we all live. There is TV and lots of other transmitters there so is difficult. Reminds me of a mini Mt. Wilson. At Wilson I cannot even key my CHI radios- only Motorola and some better radios will operate in the high rf environment there.
    I am just passing along info.

    So the commercial filters above seem to only attenuate 6dB
    I found these for $99 and there is one that looks to have 50dB of attenuation!?!
    >50dB filters for 5.8GHz for $99!

    Looks promising!!

    The sweep shows (approximately):

    -20 db at 5.6 and 6.0 GHz
    -30 db at 5.5 and 6.1 GHz
    -40 db at 5.4 and 6.2 GHz
    -50 db at 5.3 and 6.3 GHz
