I used a BN86 with a Mosley TA33JR for about 25 years. A couple of years
ago
I got a new Hygain TH3MK4. At that time I replaced the balun with a
generic
1:1 current balun. Either one will work just fine, although Hygain does
not
recommend the BN86 for high power use. What they do recommend costs an arm
and a leg. The BN86 should be OK for anything less than 1KW.If you do buy
a
new balun, make sure it is meant to be used with a beam; that means it
comes
with a boom mounting bracket.


Thanks for the reply. I did get on the internet and found the mk4 book. It
seems there is a setting about halfway between the phone and cw segments. I
guess the mk3 could be set that way also. I think I am going to try that in
about a year when I move and get a tower back up. I will probably use it
for phone but would like to have it set for a reasonable swr on 20 meters
down to about 14.07 for the digital modes. The other bands I don't really
care about as I work mostly weak signals on 2 meters and above.

No more than I use the DC bands I am not sure why I got it but it looked
almost new and was about half price..Last hamfest of the year for me and had
some extra radio money :-)

Ralph,
I think I have mine set on the compromise setting. I measured the SWR with
an MFJ269 at the base of the tower. Feedline is about 50 feet of RG8FOAM. I
get

14.07 MHz SWR=1.5
14.175 1.1
14.225 1.2
14.300 1.7
14.350 2.6
Virtually all of my operation is between 14.175 and 14.250.
