Just read all msg on the g5rv question (wow) so let me introduce my
problem - I bought a shorty forty 2ys ago at a hamfest, now Im ready to use
it:

I have two poplar trees about 150ft fm house about sixty feet apart
(perfect) and a garden shed underneath almost centered. The shorty forty is
fed with (not measured) twin lead with a female coupler for a pl259 to get
to house. I have about 180ft of catv (75 ohm) . Question: should I use a 6
to 1 balun attached to shed or should I just attach the catv to the ladder
line and let it go. The vendor of the shorty forty assured me that I just
had to attach normal 50 ohm coax to the connector and I was ready to go. of
course I have a good tuner and used it many years with a van gorden g5rv and
did great but the van gordon came with a balun at the end of the twin lead.

thanks - george
