[TenTec] It's getting cold. Perfect antenna weather for a OCF dipole

Back in 1997 I bought a OCF, which was called a TNT Windom made by 
Antennas West, that I still use today.  It is 135 feet long has a balun 
& isolation choke made of ferrite beads.  I don't know what balun he 
used, but this antenna is rated at 500 watts PEP & no tuner is needed 
except on 30 meters which is 3:1 SWR.  I use this on 75/80, 40, 17, & 12 
meters.  Have a beam for 20/15/10 meters, but have used it on these 
bands with no problems, just the beam has better gain of course.

If on SSB I run around 350 watts on 75/80 & 40 meters and never had the 
ferrite beads to cause any problems.  I did, by accident, run 900 watts 
out on 75 meters and did melt the coax under the ferrite beads.  Had to 
cut a foot off coax and move beads down, but they handle 350 watts with 
no problems on SSB.  On CW or digital I usually run QRP, 3 to 5 watts 
out, but I have operated over 100 watts out on RTTY with no problems of 
beads heating up.

I want to say the balun is a 6:1, but I can't seem to find the 
instructions. It is 43 feet on the short side, which I have to run as an 
inverted V to stay inside my yard and the 92 foot is horizontal.  Apex 
is up 25 feet. It came with 97 feet of RG-8X coax and the antenna wire 
is insulated #14 QuietFlex.  All for $89.95 ready to install with coax 
connectors.

Antennas More bought Antennas West out & list the TNT on their site, but 
I don't know if it is the same quality.  I know they have one that the 
ends of antenna wire hang down but, I know 2 hams that tried it & didn't 
like it.
