I swept my T-12 with my rig expert AA-230 analyzer and it was below 2-1  across the 13-30 mhz. range. Not sure what you are talking about, OR WHAT BRAND. But to say mediocre SWR is a false statement.

When I had a Tokyo Hy power 1.5 Kfx, the power was rolling back by as 
soon as the SWR started to climb above 1:1. by 1.3:1 it was down over a 
100 watts. At 2:1 it would have been down by 300 or more IIRC.  I would 
run a tuner on anything over 1.3:1.

My Quadra doesn't appear to be any more tolerant.  Unfortunately the 
Quadra is now ailing.

When I used tube gear, 3:1 was tollerable
