Site has been renamed after my call sign since I no longer make the antennas. Updated 23May 2012
KL7IPV antennas made for QRP and portable use
This NEW antenna fits the bill. Now here is a lightweight portable antenna that fits the needs of QRPers & portable operation and can be also used in attics where CC&Rs restrict antenna use. It is NOT designed nor meant for operation on a vehicle in motion.
I make my antennas from simple materials that require no maintenance and can be adapted for portable use, QRP use and when there is no choice allowed due to CC&Rs or other restrictions, it can be placed in an attic.
The antenna is a made to order multiple band antenna that uses a "wander lead" attached to a band of hook&loop material with elastic to hold it tightly to the coil to choose
the band you wish to work. If you have an antenna tuner, the wander lead is placed
at the bottom of the antenna coil and moved up until the loudest noise is heard in the receiver. Then the tuner matches the antenna
to the frequency you wish to use.
The overall height of the antenna with the 4 foot whip is just over five feet. If
you wish to use another whip on the top of the antenna, the standard 3/8"X24
thread is there allowing use of longer or shorter whips. For transporting the
antenna, the whip simply unscrews from the top and the antenna is ready to
go. The length of the main antenna body without the mast or base is approximately 14 inches.
The antenna base is a SO-239 that allows the use of a PL-259 to connect. It can be used on a spring mount, a flat plate mount or clamped to
a post. I use a small MAG mount for testing the units after I assemble
them. No radials or counterpoise are used during the tests. With use, you will find your own ways of operating them that fit your own needs.
Being a lightweight antenna offers many options for use where other heavier antennas would
require a heavier duty support. But being lightweight does not compromise the sturdiness of
the antenna. The coil is a eighteen gauge wire coil firmly fixed to the PVC body. The internal
wiring between the coil and the top and bottom of the antenna uses a minimum fourteen gauge wire
and so does the wander lead to the hook&loop material. The internal wiring is crimped to connectors at the top and bottom. The bolt that holds the top whip adapter on is firmly set and
uses a thread lock to keep the unit secure. The lower threaded rod also uses thread lock to keep the internal
nut from coming loose while in use. Thread lock is used on any place that has been tightened
and has to remain tight.
I have just completed making this new, very small portable antenna which is pictured here. I used it this week ( 31Mar11 ) with my IC-703. It worked great! I heard many stations with it including Alaska which I have not heard in years. I call it the "Hook'N'Looper" vertical antenna. As I refine the design I will post more photos. Here it is along side fo the original black antenna. I will be updating this site for the next few weeks.
