Tuning the sloper

Last weekend I spent several hours trying to tune up my antenna for lower bands, Alpha-Delta DX-B quarter wave sloper. It is a quite narrow range antenna, and initially I did not have time to tune it for all bands, so I ended up with DX portion of 160M band (around 1,83MHz), and some rarely used part of 80M band, around 3,65MHz. On 40M the resonant frequency was around 8MHz with some insane VSWR inside amateur band. The 30M was not a problem at all though.

The snowstorm again

Last Saturday we got snowstorm again: more than 16 inches (40 cm) of snow, and the winds around 25 mph (11 m/s). Now it’s pretty cold here, about 0 F (-18 C), even less during the nights.

Going 160M

With my original dipole, there was no way I could work on 160M. However my new sloper is supposed to work on this band. For the first I was very skeptical about it though. Still I was able to tune it for 160M, although in very narrow range.
