Rgu59U or RG400

[Lyndon]

My transponder antenna and G3X antenna. Experimental aircraft. 

$20 vs $250.

Happy to pay the extra if needed.

400 is the way to go in my opinion, better inner cable quality.

What length are you chasing, I may be able to spare some.

[Lyndon]

A fair bit. Around 16 feet. 

Thanks for the offer but I just bought it.

Thanks Lyndon

RG59 is 75 ohm coax NOT 50 ohm.

RG400 is what you need to be using. Its a double shielded teflon coax at 50 ohms. Less loss that RG58 which is 50 ohm coax.
