I had the arrow 2m/440 j pole up for about 6-8 months and had no issues. Mine was on a 5ft peice of PVC pipe connected to my 6ft privacy fence. So effectively my antenna was bracket was 9 feet off the ground with the tines going up from there. I got great reception and could hit all of the repeaters in central Ohio. I even would hit afew that were 50+ miles out (if I cranked the power up to 50w). But normally 5w would hit everything I would want to hit. Hope this helps.
