Rick, It should be the same as a CG-109, Swinging choke 5-25 H, 500ma, 52 Ohms DCR, 7KV Bill, KB3DKS -----Original Message----- Subject: [AMRadio] Transformer/Choke Does anyone have a reference for a UTC PA-109 choke? All I've found so far is UTC Varimatch Transformer manuals. I'm just wondering what the inductance and current rating is. Thanks, Rick/K5IAR
