Thanks to all of those who have helped me already with questions that I
have had in designing my tower installation to date. Your inputs have
been most helpful.
I would like to get a recommendation from the group on mast tubing. I
know that the range is from cast iron pipe to pretty sophisticated
stuff, but I would like to know the typical, or standard item to use. I
am mounting a Pro-67B (no comments about the pros and cons of it please.
I don't want to open that discussion again!) On a 2" section about 5
feet above the tower top and to continue up for at least 3 more feet. I
then would like to reduce it to 1 1/2" and mount on a horizontal 1 1/2"
section for some 2m/70cm vertical yagis for directional/satellite work.
Finally, I want my omni 2m/70cm mounted above that.
Some tubing, hardware, and spacing choices from your mental archives
would be appreciated.
Last question:
Does anyone have experience building an erection fixture for tilting up
the LM-354HD crankup? I can't buy the pre-made one because of cost, and
I have access to a wide range of welders/power tools. I have some
ideas, but would like to solicit some from the group.
Thanks in advance,
Dave KG7EW
