I was considering a hexbeam, but since 10 M is my only band of interest at this time, I decided a monobander will fill my needs at least until the end of cycle 25. Afterwards, I may rethink installing a hex. For now, I'm still wondering where to mount it and how high would be the minimum. I'm still thinking 30 feet, but it only weighs 10 Lbs, and the rotator weighs about 8 Lbs., so the support should be about the same as for the hex. I may even consider a short chimney mount. Fun stuff.
