Hi all.... Currently I am using a TT 238A tuner, its internal balun and tuned feeders for a 230 ft horizontal loop. SWR in tuner bypass is never higher than 3.5 to 1 ant that is only on 40 meters. What can I assume tuner and balun losses would be? Currently I don't run an afterburner. Will be using the 238A until I can locate a Palstar BT1500A
