Our patch-leads use MINI8 (aka: RG8 MINI) which offers improved performance over RG58 in a cable that's just 7mm diameter. Perfect for short VHF/UHF radio/coax-switch hook-ups, linking your transceiver, ATU, SWR Meter and other accessories in the Shack or out "Portable".
Choke Option: An FT240 ferrite toroid in 31 or 75 mix can be added to the patch-lead if it's to be used indoors (or in dry /P conditions). 75 has better performance below 10MHz (eg: Doublet for 160-80-60-40m), but for a general-purpose HF Choke, 8-turns on a 31-mix is best. The overall length remains the same, so you can specify this option on any length. We also produce a 1:1: ATU Choke.
