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.
