On my QRZ Page, you can see the counterweight I added where the hand grip used to be. It's from some exercise equipment that was no longer in use. It's tie-wrapped to a paintbrush handle and shoved into the end of the Arrow and held by a screw. This equalizes the Arrow weight on the other side of the tripod mount.
The attachment to the tripod camera mount is a homebrew plate of thick bakelite. Two screws are countersunk and extend through to standoffs which then attach to a thin plate. The plate is bolted through the shaft of the Arrow.
This assembly allows quick attachment to the camera mounting which has a lever to hold the foot-plate. The entire arrangement provides AZ/EL and V/H for the Arrow and eliminates the requirement for a third hand during SAT passes. ;o)

After receiving my Arrow last year I suggested by email to Steve at Arrow that a counterweight add-on would be a great companion product option for tripod use but, to my knowledge, he doesn’t offer one.
Please share your counterweight designs.

I put a counter weight type setup on mine as well. Helpful tips/ideas from K3RRR & KG5CCI to make a place to attach my D74A and duplexer; they make great ballast!

I believe it comes pre-tapped with a 1/4-20 hole. I didn't like the positioning, so I machined an aluminum "saddle" that bolts to boom, and that in turn is threaded onto the tripod mount. I also machined an extension and counterweight that makes manipulating the antenna much easier.
I have had my Arrow ll antenna for a number of years now. I have seen probably hundreds of these mounted to a camera tripod using different methods. Does anybody have an easy design they might share? 73's Jim WA5QAP
