Love the Channel, Educational even as a Avionics Installer. Keep putting this type of videos out, put a video on how to build a master wiring diagram for an installation out.
I assume this is an ADS-B antenna? It works in many situations, not necessarily ideal but factors such as coax length and shadowing become a question. What antenna is it?
A common convention in large planes is that the Com radio which is used mostly on the ground has its antenna on top of the plane, while the Com radio which is used mostly in flight has its antenna on the bottom. I’m considering installing only one Com radio. I happen to have a dual VHF / GPS antenna which I plan to use for my Com radio and GNX 375. Considering that dual antenna would, of course, need to be installed on top of the plane, is that a bad idea for a single Com radio, or does it not really matter that much?
It won’t really matter that much, maybe if you were directly on top of a transmitting antenna you could have an issue. Cessna mounts both antennas on top of the the fuselage between the wings with no issues.
Hi, I want to make an external quarter wave ground plane antenna, mainly to monitor frequencies 118.000 MHz to 136.975 MHz (aircraft band). As far as the 3mm welding rod is concern, is bronze better than aluminum? Also, when using the antenna calculator to determine the length of the radiating element and radial elements, what frequency will I input in the calculator and will I retain the 0.95 velocity factor?
Both materials will do, it must be a conductor. Aluminum is more corrosion resistant. Use a frequency in the middle of the band where you expect to listen the most, low part or upper part. Velocity factor is more of a concern with antenna cables (do not use RG-85 please).

Thank you so much for the information. I am building a BD 4C with MGL avionics already installed. I hope to see more of your new videos.
Kinda like with CB and ham this is cool knowledge to know I love it
Great info! I’ve an old Beechcraft wing style on top of my plane...would like to streamline it!
Excellent video! Best, concise info I've seen on the subject. I installed my USB GPS antenna in my fiberglass wingtip. Is this an acceptable location?

@@MidwestPanels The ADS-B antenna is from UAvionics Echo UAT.
