    ^Yes, that will work well.
    If it is broken, fix it. if it isn't broken, I'll soon fix that.

    Hey I was wondering why you wouldn't want to produce this and sell it? I would buy one. Using 1.3 with Naza+GPS is a pain. It also affects ezOSD. Anything over 300mw seems to make locking onto satellites very tough. I would think there'd be some decent demand for this if it worked. But I'm already using a notch to filter out 2.4 harmonics from my 1.3vtx so I can more safely use my 2.4 radio. Could a notch be built to filter out both?

    ^If I could manufacture it without too much trouble, I would. However these filters are VERY difficult to build. I am chasing other needs in the FPV World right now. With a little luck, you might see a whole new video frequency from me

    We have option B now - not that it's much easier than building the notch filter.

    Very interesting.. thanks for that.. Would rather pay $20 or so for a fix then go in there and risk damaging my GPS though. But I'm going to keep it in mind!

    I am bringing this thread back from the dead.

    Alex, why is the length of stubs 1.25" instead of 1.303" According to the math 2053/1575 = 1.303

    I am using RG316 coax

    Can I get you to reconsider making these?
