    Hidden stealth aircraft antenna

    There are several reasons not to mount a transmitting antenna is a steel cage. First, all of the steel tubes will interfere with the transmitted pattern and de-tune the antenna to increase the SWR (power reflected back to the transmitter, not radiated from the antenna). Second, the firewall at...

    Hidden stealth aircraft antenna

    I'm sorry to report that my Tailwind is not to that stage yet -- but I'm hoping to load a wing strut similar to a J-pole antenna. I'll report when I try it.

    Hidden stealth aircraft antenna

    There is considerable difference between using a 20 ft. antenna for a frequency whose ¼ wavelength is 600 ft. and an 11" (steak knife?) one for a frequency whose ¼ wavelength is 22". Two days ago I "worked" a station in Hungary from OK using a 550 ft long wire loop on a frequency whose ¼...

    Off airport operations, where is it allowed?

    What about the sand bars in the area rivers that the STOL guys like to show videos of? How do you find out who controls them?

    Fighter Pilot looking for advice on the GA world

    When we decided to get back into GA after raising four kids and sending them to college, I looked back at our boating experience - driving out to the lake, assembling the sailboat, launching it, retrieving it, disassembling it, trailoring it back home, rinse and repeat. We found a...

    Just Built a Stratux -- Some Questions

    I also "Upgraded to the Pi3B with the onboard WiFi, smaller nano USB receivers for both 1090 and 978 antennas", but not the GPS. I mounted the Stratux under the panel, one transponder antenna on an inspection plate on the belly with coax running up to a Y that then feeds both receivers. Yes, the...

    iPad choices, small single engine GA

    I just bought this tablet - https://www.tripltek.com/tripltek9 - and it is far and away the best one I've used. I dumped the iPad mini after it overheated in flight, then Tab-A did the same. The TriplTek is marketed to the commercial drone fliers - out in the full sun all day. It just works and...

    Flight planning app that doesn't require Apple device.

    I am VFR only, and use iFly, Weathermeister and Windy for flight planning, with AirNav for FBO info. I use iFly in the air running on two devices - an iFly740 dedicated device and a Samsung Tab A on the other side of the panel. One is portrait and the other landscape. I really like the old...

    Handheld Radio with External Antenna from Home Question

    The performance of the j-pole and a ground plane should be the same. The differences are: the j-pole (½ wavelength) is twice the length of the ground plane (¼ wave length) so mounting space might be an issue. The j-pole can be directly connected to ground, the ground plane needs to have the...

    Handheld Radio with External Antenna from Home Question

    Jim Weir also published the dimensions and directions for making an air band antenna with copper foil tape that is supposed to be very good - it will require a ground plane of some (any) sort.

    I am waiting to see if the new control box has the grippy coating or not. I hope not.

    Lightspeed Zulu headset sticky control box fix?

    The control boxes on both of our Sierras turned sticky. I wrote to Lightspeed and they offered to replace the sticky bow at no cost and do an inspection. If they find something wrong (long out of warranty), they will let me know and give me option of having them repair it or not. As these are 9...

    GAMI vs Swift UL fuel competition

    I would be happy to use either or both - just get the lead out! It seems that big oil is pressuring the FAA/congress to slow down - change costs money and they have plenty of 100UL to sell that they don't want to have to dispose of. GAMI is planning on licensing their formula to whomever wants...
