I am a user of an Arrow II handheld yagi. I am also very impressed with it's performance. Has anyone attempted to weatherize it for permanent outside tower use? Seems a little Loctite on the element threads and some shrink wrap around the BNC connectors, pull the foam handle and mount it. Anyone try this?

Exactly right Jim. I did everything except the loctite and had mine up for over a year on a TV rotator. I just screwed the elements together as tight at I could with in reason. Some of the FM birds will have unsatisfactory passes from time to time as you can't adjust for polarity or give the beam a little twist of the wrist. So you will get some fading from time to time . Sometime you might be deaf for half a pass. But that experiment was enough to get me hooked and upgrade to a cross polarized and switchable antennas on AZ/EL rotators.
BTW, I bypassed the built-in duplexer and ran two feed lines when the handle was removed i.e removed the foam handle and duplexer and shrink wrapped the BNC connectors. We have -40C to +40C weather here and it survived okay. The only way you know something odd happened to my arrow is the wear and tear after a year on the elements in that the colored speckles on the top side of the arrows faded to the pure aluminium. It's now back to field day and demo use with the foam handle reinstalled.
I even added a DIY elevation control rather than fixing it at about 30 degrees by using an remote controlled electric auto mirror assembly picked up at a local surplus supply house for about $5 plus a bunch of PVC plumbing stuff from Home Depot.

However, now that I have a couple of KLM's on a Yaesu G5400b with Landwehr preamps...well, there is no comparison. I think that sooner or later everyone comes around to understanding the importance of good antennas and feed line and installed the best you can afford. I appreciate that budgets and physical location sometime will prevent an optimal installation. My KLMs are shorted to they clean my roof, but, that is for another discussion.
