I have a Di Pole that was in the same condition as the antenna you presently have.

Someone took it upon themselves to fix it with a type of fiberglass epoxy and some glass mat and some gel coat.

The person that gave me the antenna assured me that it worked properly and it was adjustable for all 10 - 11 meters.

Not really a screw driver type antenna, but it has a two nut adjustment at the base.

I have a very old tube type 10 / 11 meters radio called a Siltronix 1011D - Comanche and the other day, after solving a problem with some used coax I bought - I was able to talk to a guy in Alabama with 60 watts output @ 1.2:1 SWR and he told me that my signal was 30 over S -9 and that my modulation was hot and that I needed to turn down my mic gain.

I also talked to twp people on the chicken band after I put the antenna up 20 feet AGL and some local operators said I was 30 over S-9 and that my audio was really hot and I had the amplified Turner Plus 3 mic turned down half way and the radio turned down almost the whole way on the mic gain.

So since the gel coat was deterioriated to the point of where the fiberglass was coming off in my hands, I took it upon myself to go down to the Dollar General Store and buy several can's of white paint.

It was white or black - because that was all they had on stock.

I had a can of Krylon universal paint and I applied one coat of RED paint between the coats of white - so as to be able to see when the top coat of white goes bad the red will show.

I added a couple of ground radiators - since it had none and I put 3 independent ground stakes attached to the mast pipes and my output is very good.

So I would think that if that antenna lasted that long the way it was, and if you were willing to do some work to modify it to make it stronger and put some resin over the antenna to protect the gel coat that it will probably last longer then you will.

I was skeptical of putting up a dipole antenna 16 feet + tall in the mountains of Pennsylvania with all the high winds we have here with no guy wires on the 1 1/4 rigid conduit I used to attach it to the side of my garage - but the 35 - 55 mph winds we had this week was no match for the antenna and mast pipe - because it never even bent or contorted.
