Time: 2 Hours
I started the the time in the shop priming and riveting the parts together that made up the transponder bracket and put it into position. I had received a package from Aircraft Spruce the other day which included several different parts including the ones I needed for the antennas.
The parts I would be using is RG – 400 cable (similar to cable tv wire but aircraft grade and has a braided center core vs a solid wire) and crimp in BNC connectors. I watched several videos, including SteinAir, on the process of making these cables. After feeling good about the process I went about making my first one. The BNC crimp ons have three parts, the connector, the crimp sleeve and the pin.
I crimped the pin then slid the sleeve in place. The connector them slides on and under the braided wire. You push hard enough to feel a snap as the pins ridge catches on the connector. Slide the sleeve back to the connector and crimp. Then check your crimp to check for a short between the pin and the shield.
I then figured out the final length needed for each cable and cut. I then put the cable in its place in the fuselage going through all of the snap bushings. I didn’t repeated the process of adding the connector on the final and as it’s now in place and not forgetting to put the label on this and before crimping. I secured the cable alongside of the flexible conduit with zip ties and put the 90° adapter on the end that will connect to the actual antenna. I left plenty of cable in the back to connect to the radio’s when they get installed.
A new skill learned and feeling accomplished!
