Hi Graham, G3VZV
Recommended types are 50 ohm semirigid hand formable coax cables with
outside diamters of 0.86 mm , 1.2 mm and 2.2 mm with SMB or SMC
connectors and 3.6 mm with SMA connectors.
See the catalogue http://www.rfmicrowave.it/catalogue.php?lang=eng
sections COAX CABLES and CONNECTORS
Various characteristic impedances are available, 12.5-25-35-50-70-75 Ohm
