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
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!

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.

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)

The MFJ diplexer makes a decent counterweight, and is likely lower insertion loss than the in-handle one sold by arrow.

I use a piece of 1/8 in thick by 1/2in angle aluminum about a foot long (scrap from my metal pile, available at Lowe's/Home Depot/Ace Hardware/etc.). I tapped a 1/4in by 20 hole in it for the tripod camera mount, and then use two hose clamps to attach the foam grip portion of the arrow antenna to the angle aluminum. I use pretty sturdy all aluminum Velbon tripods (Ebay), so no counterweight needed. If the 1/4 threaded attachment isn't 'sturdy' or is difficult to get nice and tight, then you can get a side to side slip of the antenna around the 1/4in tripod screw, particularly when you rotate for polarization. To resolve this I added two small pieces of 1/16" angle aluminum on the 'underside' of the 1/8" angle aluminum to 'grip' the front and back edge of the tripod 'plate.'
