I had a stack of TH7's for many years...BN-86's died and I replaced with
the BN-4000.  No problems ever with these...Almost indestructible.

TT Gang,
It looks like my BN-86 Balun used on a TH7-DX beam is giving me grief.
antenna was assembled to use the DX or lower portions of the bands. The
measurements are good on 20 meters, but on 15 and 10 meters the SWR is
on the CW portion of the band. After doing some basic research and
with a friend we have come to the conclusion the Balun may be causing my
problems. I am considering a new Balun for as a replacement from DX
Engineering. DXE have several models to choose from so I will have to
through the details, but several obvious questions come up. 
How do you mount these Baluns on a beam and is the ground strap still
required for beam mounting or does one 'float' the Balun electrical
Which DXE Balun model works best on the THY antenna?
Are there other Baluns I should consider for using with the TH7 antenna?
Thanks gang,
Eric - VE3GSI
