[Elecraft] Beam antenna

Maybe worth looking into Mosley mini beams if weight or wind load an issue.
I installed one last year.
I have enjoyed the results but antennas can turn into a religious argument.
I have limited backyard space so I needed to compromise. Mine is on top of a 33' telescoping aluminum mast attached to the side of the house. Rotator at base.
The 4 element beam (3 elements on 10-15-20 and dipole for 12 and 17) weighs less than 16 lbs on 6 foot boom. I liked the idea of 5 band coverage.
It's performs far better than my R7 but have not compared it to a hex beam.
I have heard good things about hex beams but was bit concerned about potential maintenance issues.
I do not run it on high power. So if you are QRO I would not recommend it.
Just my 2 cents.

> I have a Traffie Hexbeam (Traffie retired and the company is no longer in business) and it has been up for about 12 years. My last check of the elements, coaxial connection and so on showed no problems what-so-ever. Operating performance seems to be just as good today as when it first went up in 2005. Weather has been rain (mostly), sun with high temperatures reaching into the 90s usually in August (one recorded day at 103 though), and snow once or twice a year but the snow never lasts for more than a day or two at most on the antenna.
