I see all kinds of crazy matching sections in posts about 6 meter
beams. How about direct connect. I have an A4S that has major issues
in the traps and I cant find the problem (IE I opened them and cant
find anything) SOOO I have a new A4S coming.

Has anyone taken an old 3 elem tribander and converted it to 6 meter
monobander using the direct connect.

Any Issues.

Would a 4 elem be better since its a long boom ?

I'm pretty sure I know the answers. Just want to confirm and see if
there is any reason not to direct connect rather than through a
hairpin or a gamma match.

I have an old Radio Shack 11 meter 3 element beam that I plan to put
on 6 meters. I once did the EZNEC modeling with the boom length being
the only constraint. It was possible to come up with a model that
would work with a direct match for 50 ohms to the driven element. I
hope to try to construct it soon.

The problem with holding a few parameters constant is that you have to
accept whatever gain, patterns and such that come with the deal.

I also have a very old Mosley 15 meter 3 element beam that I want to
modify to 17 meters. I am having a lot of fun with PSK31 there with
poor antenna setup now.

Tower space is a limiting factor in my case and I am not interested in
anything that compromises my A3S!

I wish you were close to me rather than 2306.9 miles, I am looking for
an old bargain tri band to tinker with. There is a lot there I don't
understand!
