Indoor Helical Antenna for the 20 and 17 meters for K1: by: Igor Grigorov, VA3ZNW
So, my Ê-1 with 40, 30, 20 and 17 meters bands was successfully assembled and tuned. This
one requires an antenna to go to the Air. Certainly, an antenna is a simple thing if… if
you live in a private house. But I live in a multistorey apartment building (made from concrete)
with huge large restrictions on installation of antennas. The result of these restrictions is
those, that I can install an antenna only at a window. Good sign is that in mine apartment the
windows are big sized- 150 to 210 centimeters.
