This I guess answers a question I was going to ask. I have 20 ft of r25
bracketed to my garage at abt 12 ft. My plan was to put another 10 or
maybe 20 ft on it unguyed and with a haze for a 6m5x and as a support for
an 80m edz of abt 340 ft. No climbing would be needed except for
installing the two more sections. I was not planning on guying this but I
guess I should. I could probably do temp guys for installation.
