    They usually perform every bit as good as the bluebeams, working with tree to know what might be the cause. At fisrt, I believed my units would have bit less range because they have a bit less gain, but that didn't show once out in the field.

How do I know? Volto and I built them for the TV production industry. They lasted about 3 days until we made the radome float. I highly suggest making the radome twist independent of the element inside. Bonding it to the coaxial cable works fairly well, though. I opted to make the entire radome a completely separate assembly.
    Thanks Alex, we tried various ideas, this one seemed to withstand abuse the most, and we really put it through the wringer. But we'll see how people like them and how well they resist abuse in the field.

    one question. on these antennas or any antenna- are you guys putting the rx antenna on your goggles at a 90 degree with a right angle elbow? to raise above your head a little. or straight out. mine is straight out. but ive seen both.

    I'm going to use the right angle adapter.

    Using the antenna straight out might well explain your drop out at close range. It need to be held upright away from your head.

    I've noticed with turbine/fan or turbine/turbine there is some static when flying directly over myself, with both antennas oriented so the center conductor is vertical and feed is below. I knew to expect that before flying, as Hugo has released simulation data for his antennas. I'd like to see some data for these antennas too!

    Noticed these antennas on Simons site and came looking for more info. Got a whole lot more, shame.

    Are they only available in a set? I've been having more success at distances with SPW (4 lobes, better clarify after all the previous) so if i had the choice i would only buy the SPW's. Like the radome, I've seen ping-pong balls opened up and used as covers, makes sense on quads if you like to land them upside down occasionally

    It's always a mixed bag where your success lies. For me a cloverleaf on each end works best. Some prefer 2 skew wheels. Most prefer a clover and a skew wheel mixed. The Ping pong balls work well if you can get them glued together. The issue is when you wreck, making sure the antenna deflects and doesn't rip the SMA jack out of the VTX.

    If it is broken, fix it. if it isn't broken, I'll soon fix that.
