According to the Rohn catalogue, you can go 35 ft above the bracket.  I have 40 ft of 25G i used foe my WARC A3WS. Started with a Hygain TH3 till I got the big tower up.  That was 35 years ago.

Section and attach a house bracket at the 14 ft level. This will leave the second section unguyed for 3 ft above the house bracket.  How many more 10 ft. sections can I add safely above that point?  My antenna will be a Mosely TA33-Jr (27 lbs) wind surface area 5.1 sq. Ft. Windload 98 lbs at 80 mph.
