I only looked at a few frequencies but those were near the frequency for
which the antenna was cut. I¹m not worried about the other bands. I want
to know why I did not get a higher S meter reading on the band the
antenna was cut for. The transformer should have made for a better match
on 13 meters and it didn¹t.

I mentioned in an earlier post that the folded dipole I modeled showed
a low Z. But after thinking about it, that didn't seem right. I had
always assumed most folded dipoles with two wires had about a 300 ohm
feedpoint. And double checking in a book, that seems to be the case. I
don't know why the antenna I modeled showed that, but I'll have to
look into it. But anyway, if you had a 300 ohm feedpoint, and used a
9:1 balun, you would end up quite low in Z to the radio.
A 4:1 would put you in the ballpark. But, I'd still prefer to use a
single wire dipole fed with coax for a single band dipole. No
transformer needed. Only a balun, and that can be a choke wound from
the coax. But again, as far as s/n ratio, not counting noise ingress
problems, any of them should work. MK
