[Elecraft] Coax-Fed Antenna for KX1 with ATU

Mon Dec 22 09:51:01 2003

Phil,

My dedicated KX1 antenna might be food for thought. I will describe the =
40 meter antenna first: It is a sloping inverted-L. It goes vertically 7 =
feet up a plastic pole and then 26 feet to the peak of the roof. #26 =
wire. It has a few radials and a ground rod and is fed with coax into =
the bedroom. The 20 meter goes up vertically along side the other one =
(spaced 1' at the top of the pole) then heads off to the other side of =
the house. These seem to work well. The simulated radiation pattern =
looks good. 30 meters could be added.

Subject: [Elecraft] Coax-Fed Antenna for KX1 with ATU

I like using my KX1 in my living room, about 100 ft from my ham shack=20
where all my existing HF antennas are fed.  I've tried various wires and =

they load well enough, but do not hear or get our at all well --=20
probably because they are not up in the air.

So I'd like to put up another (not too ambitious!) dedicated antenna for =

use with my KX1.  Criteria are:

o Coax fed: I have a coax line from the front porch thru the window sill =

now, and must route it around a doorway, etc. -- so ladderline is not an =

attractive option.

o Loadable with the KX1's ATU on 40-30-20 (this may be the tricky part).

o Possibly off center fed (location is at one end of my lot, making a=20
symmetric antenna more difficult to locate)

o No convenient place for a vertical or anything which goes up like a=20
Skelton (it would be right next to the HF beam on the roof)

I'm thinking of a Carolina Windom sort of antenna, perhaps commercial, a =

40-10 version.  But I have no clue whether the KX1 ATU has the range to=20
load it on 40-30-20.  A short (51 ft) G5RV is another candidate I could=20
accommodate, but do not know if the ATU will load that either..

So does anyone have experience using the KX1 with in-board ATU with=20
either of the above antennas?  Any other suggestions for coax feed?

73, Phil
