Arrow Antennas for terrestrial work
Most of the reviews I have seen for the Arrow Antenna dualband yagis are regarding their use on the satellites, which I think is what they are mainly made for. Has anyone on the list used one of their dualband antennas mounted permanently for terrestrial work as well? They do sell a mounting bracket for permanent mounting to a mast.
Do they seem well made enough to withstand the outside elements for a few years on end? Do they seem to perform as well as other antennas which have approximately the same boom size and number of elements?

I have used mine multiple times for terrestrial contacts, SSB during January VHF contest and FM into repeaters too far away to work with a vertical on my car.
There is a mast mount, which I have used, but only as a temporary setup. I could see the gamma matches not working well for a permanent outdoor antenna, and the elements might get loose over time with temperature differences. It is possible that this would not happen as the differences would not be as extreme as going from indoor-outdoors.

Besides the mechanical issues that others have noted, one thing to consider is that the 2m / 70cm elements are at 90 degrees from each other. If you want to mix repeater and weak-signal uses, you may need a way to rotate the beam so that the polarization is optimized for the band and use you are engaged in.

In my opinion, the Elk Log Periodic is better suited than the Arrow for permanent mounting.
The downside is the gain on 70 cm compared to an Arrow. Even then, it will work. I used one during the June VHF contest and was able to work UHF with 20w to the same places I did on VHF with 50w (around 250 miles).
A plus is having both bands on the same polarization.

I had an arrow antenna outside for years on my roof in Brooklyn. So in all weathers. +30C to -20C. You need to seal the matching stub or water can get in. As others have mentioned the elements will seize in place and rust. So you can't take it down later and reuse it. You have to cut the elements off. Otherwise they last a few years for sure. So if you have a spare one that is otherwise going to waste, you can use it. Otherwise an antenna designed for outdoor use is better.

I agree with Fernando. I used my Elk during the winter VHF contest and for VHF/UHF simplex work on SOTA. The mounting is easily rotated to accommodate vertical or horizontal polarization
