The cable was of high quality but was very hard to install the connector I ordered with it. Had to revove some of the vinyl jacket and expose the braided shield to get it connected to the BNC connector.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: What is the outside dimension of this coax?

3/16"

Q: Comparing RG400 and 142 Which is best for VHF and which for GPS?

RG 400 (11-09202) is made with stranded wire and is good for both VHF and GPS. RG 142 is made with a solid wire and is better when running long lengths typically over 15 feet.

Q: Is there a minimum length of RG 400 for orders?

No, we do not have an order minimum for the RG400 cable.

Q: Can this RG400 coax cable be used for all aircraft antennae like glides slope, transponder, etc.?

Yes, this antenna cable is sufficient for most types of rf uses.

Q: 1) What material are the center conductor insulator and outer jacket made from? 2) What is the weight per 1,000 FT?

The center conductor insulator is PTFE with an FEP outer jacket. Weight per 1000 feet is 46 pounds.

Q: Is the center conductor solid wire or stranded wire?

RG400 is stranded. If you would like solid conductor, please view RG142 11-00043.

Q: I havent found a stripping or crimping tool specific to RG400. Do you offer those?

Consider looking at these two tools.
IDEAL COAX STRIPPER Part# 12-03716
COAX CABLE CRIMPING TOOL Part# 12-02378

Q: Can RG400 be connected using BNC connectors to the RG58 tail from an existing foil dipole antenna in a composite aircraft? It will be too difficult for me to access the center of the dipole antenna, so I am hoping to be able to hook up via a BNC connector

You are able to crimp a BNC to the cable for a connection.

Q: Can RG400 coax cable be used as extension cable for Garmin GPS 296 antenna?

Yes, this would be the right cable.

Q: I need 50 ft. How do I choose the length? When you press the add to cart button, there is no option of length

Since Part# 11-09202 is sold by the foot, you would enter quantity 50 and then hit add to cart. If you have already added quantity 1 to your cart, you can simply update the cart quantity to 50.
