[Elecraft] Balun for KX1 - doublet combo?

[Frank R. Oppedijk]

Hi,

I've been lurking on this list for about a month now, so I guess this is my 
official "hello" to the group. (Great group, BTW; excellent posts; am 
learning a lot here!)

In the meantime I've bought and assembled a KX1 and am now thinking about 
which antenne should accompany it on my upcoming holiday to the Alps... I'm 
considering buying one of those DK9SQ telescopic masts (as soon as I've got 
a definitive answer about the mast being RF absorbent or not; I want to be 
able to use it to put up a vertical too) so I can put up a doublet antenna 
in inverted vee mode. I don't like the 3 dB loss from 10 meters (that's 33' 
for you non-metric people out there) of lightweight RG174 coax, so I'm 
contemplating feeding with open wire.

Now the big question: how to connect the symmetric open wire feeders to the 
KX1?
a) Don't bother; just plug one wire into the hot side and connect the other 
side to the case
b) Use a balun
c) Something else.

If b), then what configuration would you use? How small a toroid would keep 
up with the torturing that it might get in such a high SWR environment?...

Thanks in advance for all the help!

Cheers,

Frank
