Finally got my Proof of Concept completed to actual build for a wideband HF portable antenna
I used a broadband un-un for wideband impedance matching – still needs a tuner, a 12 foot AT-271, 25 feet of counterpoise and coax.
I tried it across several bands with out a tuner (FT-817 didnt balk so assume the swr was not 5 to 1) and very happy with the performance and can pack up nicely into a 20 inch bag. The swr was many bars on the display.
I will showcase it at the next Toronto QRP Society meeting
