[TenTec] Zepp?

[Rick - DJ0IP / NJ0IP]

John,

The Zepp was a one sided antenna, with a quarter wavelength openwire
feedline to a halfwave wire.  The ground side of the feedline (at the TX)
was connected to ground, the hot side connected to a tap on a tank coil.

The hot side of the openwire was connected to the wire aerial and the cold
side (ground side) was left open, connected to nothing at all.

The double Zepp was then this same antenna but with the (ex) ground side
connected to a second half wavelength wire aerial, and the  feedpoint was
then typically connected to a link coupled symmetrical matchbox, neither
side grounded.

That was almost 100 years ago.
Things have evolved and the names have evolved.  Lots of aerials' names have
evolved since then.

I can't believe you get so hung up on a name.

More important is that we understand the type of antenna being referred to
and what it can do.

I can't believe that anyone who calls himself would call the described
antenna a Zepp.
I guess that since dumbing down the tests we can all call ourselves
engineers.
The Zepp antenna was an end fed antenna used on the Zepplin air ship. What
"channel" does this engineer from Ten Tec operate on??? Enough Zepp bull!!

 Just swapped the 4:1 balun out
 replacing it with a 1:1 balun. I am now  back to using a 2 ft long jumper
of RG-213 and the  auto-tuner combo  seems to work OK. Glad to see the
longer section of coax  gone between  the balun and the tuner.
 The tuner is inside the ammo can now, but it does not have a  proper EMI
gasket on the lid. But at HF freq's it probably does at  least a half ass
job of being a Faraday cage. When I ran into trouble it was  outside in  the
elements.
 The tuner still will not "tune" the doublet above 28.3 MHz  just as  stated
in my original message. At least it works on the CW  band of 10M.
 Once again, thank you for suggesting I try a 1:1 balun  instead.
