Default Metal mast for inverted V antenna support--will it work?

wrote in message news
What is the result of using a metal mast as the center support of an
inverted V
antenna. Will it work and if so can resonable low SWR be obtained using a
tuner? Any advice appreciated.

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.
