I purchased enough RG-400 to replace all the coax connections inside my amateur radio station (160-10 meter bands). Ive used LMR-400 previously. Although the crimp connected LMR-400 had worked well, I wanted something less bulky, could handle full legal limit and more. I purchased the RG-400 along with Amphenol PL259 & UG175/US reducer adapters and made the soldered connections. The change noticeably lowered my stations impedance. There is a great YouTube tutorial video on how to install these connectors, (see Mr BBI Jan 31, 2020). This coax handles high heat. I preheat my Amphenol adapters with a butane torch while soldering and the Teflon dielectric does not melt or fail. From now on RG-400 will be the only coax used inside my shack or within my mobile station. RG-400 is UV resistant. Great stuff. Dont try to save a few dollars on inferior coax. RG-400 will last a lifetime. Scott - KL7EZ Gallatin, TN

I use rg400 coax for all my ham and cb radios as jumper cables. The rg400 is the best to use. I always order my coax from Aircraft Spruce. There service and shipping are next to none. Great place to buy what you need.

I am using this cable for jumper wires for all of my ham and cb radios. This cable is perfect for these applications. Great size and flexibility. I will be ordering more.

High quality coax with smooth outer jacket, 2 braid layers, and a stranded core. Easy to bend and route. Fits through 1/4 inch grommet just right. I used this for all com, txpdr, and ADSB antennas in my plane. Very happy with this product.

Q&A

Please note, Aircraft Spruce Canada'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 Canada 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.
