Remote control for a motor tuned magnetic loop antenna.

This device remotely adjust a super light small magnetic loop antenna, that can be used at home on the balcony or during my QRP pedestrian operations when the antenna is suported on my back by a special designed back suport that can be ssen on my webpage.

Thank you very much, but this antenna is not a commercial model yet. The
commercial models are the AlexLoop SML 7-30 Kit and the AlexLoop Walkham,
that you can find on the webpage. They are QRP models designed to a maximum
power of 20 watts SSB / 10 watts AM/FM 73s. PY1AHD ALEX

Author kb0naz (2 years)
I'd love to have one. My AlexLoop Walkham works great,but a remote tune one
would be better than great. I'd get one if you ever made them available

Author huelbe (6 years)
What I find fantastic with PY1AHD Alex is his ability to come to a creative
solution from simple, cheap components. If I remember correctly, this loop
tuning controlling system began when Alex stared at a hand crank flashlight
at a dollar store! Also, all his experiments are homebrew but extremely
well built and polished. Congrats again, Alex! Well done! Huelbe.

Hi Andy, Thank you very much for your interesting information. I will check

Author valveman12 (5 years)
Nice Design. Looks like it is easy to tune unlike many other loop antennas.

Author vk3xpt (1 year)
This looks great Alex! I would purchase one for my Walkham if you make them
available. 73

Hi there, well done that looks to be a very good system you have there.
I’ve designed a capacitor drive mechanism that overcomes to need for the
use of limit switches. It’s made with simple mechanical linkages that allow
the drive motor to keep on turning yet drive the capacitor backwards and
forwards through only 180° without the need for limits. If you search my
channel for About Radio 61 you’ll see the concept then About Radio 62, 63,
64 etc show more information All the best ... Andy GWØJXM
