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

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.

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.

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?
