Sirio Vector 4000

I've been aware of this antenna for years. Lately, I've been gandering at it. It seems to have some build quality concerns. I've also noticed some fixes/mods and the like.

Seems like most people install low to the ground. Does it perform with low angle radiation. It also doesn't seem to favor much higher than the 10 meter phone portion. Does the tuning and feed point accept fiddling. I don't know if I should try one or not. Seems like a 50/50 love hate relationship.

I had one and it is not an “ easy to deal”antenna. It is looooong and picky when trying to tune it. I had it 15 feet above a rebar reinforced concrete roof. Had the coax cable attached to a galvanized pipe with zip ties. I had no less than 2.0 SWR. I played with the game and the bone with no results.

I released the coaxial cable from the pipe leaving it connected to the PL of the antenna. Magically SWR went down. I had CMC problems, probably because of the rebar.

I sold it because it was very long and difficult to handle it.

RX is about the same as a 5/8 antenna.

It's been out for years. Seems like the recurring issues haven't been addressed. I was starting to look at it. Think I'll ignore it unless I come across one locally. Thanks for the input.
