[TenTec] TT 238A tuner efficiency

["Denton" <denton@oregontrail.net>]

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
