When looking for a mast also take into consideration how self supporting it
might or might not be. At another qth I used a flag pole. It didn't
telescope but it pibited down on a mount. The only problem was I got greedy
and wanted to add 10 more feet. Thankfully I was younger then. 24 feet
wasn't bad. After adding another 10 feet of 2.5 inch heavy pipe it was a
bear to raise and lower.
