Becker Radio Becker AR4201 COM Radio Reviewed 1/20/2001 In upgrading the radios in my Cessna Airmaster, I needed a new radio but had to deal with an extreme lack of panel space. The Airmaster has no room to hang a standard-sized radio underneath the panel, and it also doesn't have much depth available due to an oil tank located behind the firewall. I did have a 2.25' round cutout available on the panel. There are two small radios that fit the micro-sized panel mounted category.

The smallest is actually the 760. The Microair is a good looking unit, however it is not TSO'ed which will make installation in a certified aircraft difficult. The Microair front panel interface is also a bit clunky in my opinion.

It shows its European roots by using metric-sized through-screws to bolt to the panel. The data connector is located on the back of the unit and uses a standard DB-25 size, which is good. The connector also uses slide-bar locking of a unique style, which is bad.

If you buy the radio new from Becker, the connector/backshell assembly supplied by Becker fits and locks very nicely. Unfortunately I bought my unit used and it did not include the connector. Buyer beware. It is probably possible to convert the unit to use lock screws to secure the connector, but this would require disassembling the unit. That was more trouble than I wanted to get into so I just called Becker to order an additional connector/backshell assembly. Trx Full Body Workout Pdf. For depth-restricted installations, the data and power connector is located in a stepped-in section on the lower rear of the unit, so much of the connector backshell does not protrude beyond the rear of the radio case. The antenna BNC connector is not located in the stepped-in area, though, so if you're worried about depth you should add an allowance for a right-angle BNC connector.
