... No problem at all. I use a steel telescopic pylon, 20 m long. It supports two inverted V's: one for 40 m and one for 80 m. The wires are kept 20 cm apart by 5/8" plastic tubing. The two inverted V's are fed in parallel through a 1/4 balun at the end of a 50 ohms cable. VSWR is almost 1/1 for 40 m. On 80 m the VSWR varies from 1/1 to 1,8/1. At least 200 kHz of the 80 m band can be within 1,5/1. Of course, the length of the elements determines witch part of the band that is. That should have been "...which part of the band that is". Sorry, my English stinks... |
