[Elecraft] RFI MP-1 antenna

[Eric Swartz WA6HHQ - Elecraft]

The MP-1 is manufactured by SuperAntennas here in California. Elecraft resells
the antenna and the full info can be found on our web page. It is unique in the
short portable antenna category because it uses a sliding coil to tune the
antenna.

I personally use the MP1 for a travel antenna. I like it because it breaks down
into 12" or less sections and fits in a small laptop PC pouch or my K2 Tac-Pac
and can easily be set up in a hotel room or trade show booth. I frequently clamp
it at a 45 degree angle outside those hotel windows that open and drop a radial
down to the ground or along the window sill. While ALL short antennas will not
perform as well as a long wire or full sized dipole, they certainly do work well
enough to make a lot of QSO's from the hotel room. (Especially on 30M - 10M
where they are most effective.)

The MP-1 has an optional longer bottom mast (in the 'mobile kit') that you can
use to increase efficiency if you have room. 

If you have room, several 33' radials increase the performance of the MP-1, and
most other shortened verticals.
