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.

That should have been "...which part of the band that is".
Sorry, my English stinks...

Sorry, one more correction: the balun is a 1/1 type.
