[Elecraft] [KX3] Info on whip antenna shown in KX3 photo

[Bill K9YEQ]

Wayne,

 

I have successfully used an ATX Walkabout.  I purchased it from a supplier
in England.  I think that MFJ has a similar unit.  I comes with a jumper and
will work to 75 meters.  I have successfully used it on my FT-817. I also
drag a counterpoise based on band.  I haven't used it for a while.  I also
us a Maldol AH C14 for 20 and 17 meters.  I have had my best success on SSB
running 2w working FL to TX.

 

73,

Bill

We've had some questions about the whip antenna shown in the KX3 data- 
sheet photo. It's a Maldol AH-C14 20-meter loading coil and AH-R 
telescoping whip. Total length is about 48 inches.

I've made QSOs of up to 3000 miles using this type of whip, handheld, 
while walking with the KX1 and dragging a 13' counterpoise wire. It's 
a very compact emergency antenna, with two parts that disassemble and 
have a max length of just over 7".

That said, I strongly recommend using longer whips for the HF bands 
whenever possible. I found that just increasing the length of this 
whip by about 1' made a noticeable difference in signal strength on 
both RX and TX.

I'm still searching for the "perfect" stealth whip for lightweight 
hand-held use. What I'd like is a nearly invisible antenna that's 6 to 
7 feet long, self-supporting but able to survive collisions with 
trees, and either telescopes or rolls up to less than 8" long. It 
should cover 40-6 meters, preferably with the aid of the internal ATU 
in the radio so there's no need to change taps or elements while 
walking.

73,
