Bid or Purchase
Current Price: 28.99 USD Ends in: 16d 14h

Custom-built coaxial cable, assembled using low-loss Mil-spec RG-400 teflon coax, a BNC male connector on one end, and an SMA male right angle connector on the other.  Ideal for a Garmin GDL39 external antenna using any antenna having a female BNC connector. This cable can also be used in com, transponder/DME, or ADS-B UAT installations when the antenna has a female BNC connector and the radio a female SMA.

Less than the cost of the quality connectors alone!

This auction includes up to 9 feet of premium 50 ohm RG-400 cable, a Suhner German-machined SMA connector with, and an Amphenol or Winchester BNC connector, each with gold-plated center pin. In addition, each connector has a double-wall adhesive lined heatshrunk strain relief. Custom-imprinted heat-shrinkable cable labels (up to 2) are also included on request, up to 10 characters long each, to be specified by the buyer at time of order. Labeling will allow you to keep track of the coax function behind your panel or in dense cable bundles, and can be unique to your aircraft!

Right angle BNC, Mil-spec female/female BNC couplers, blind mate tray, or straight TNC connectors are also available for additional cost--please contact me before purchase to make sure my stock can accommodate your request. I also have RG-393 coax available for ultra low-loss transponder or ADS-B installations.

On purchase, please specify the exact cable length, and the label text if desired. Note that custom cables will ship within 48 hours of order rather than my usual 24. This leaves time for inspection and test of the cables after manufacture.

Why buy from me rather than a mass cable producer?

I build each cable by hand, to order, using professional precision, calibrated tooling

I inspect each strip and solder joint under a microscope before proceeding

I only use RG-400-designated connectors from name-brand manufacturers, not cheaper RG-58 connectors which don't fit as precisely, or Chinese connectors with questionable gold plating and construction

I use thickwall adhesive heatshrink

I can label your cables

I can build custom lengths within 1/2 inch to suit your application precisely

I can partially finish the cable ends to facilitate your airframe routing

I can answer your aviation-specific application questions
