Double Antenna Mast Clamp V Jaw Block with U Bolts, Heavy Duty Mast to Mast Mount Bracket Kit for Outdoor Antenna 2 Sets

These Work, I have re-orderd these, Will include Pict's on next Review.These are excellent for tying two masts together, also for attaching other items to a mast

Great set of double clamps, easy to use, very functional, worked great for our application and a good value for the price.

Used these to attach a longer antenna pole to a Dish Satellite mount. I ended up buying some extra nuts so I could first tighten these to just the Dish mount and then work with the second longer pole. I saw this done on another more expensive mount, so I upgraded this mount. Otherwise, it is hard to work with two loose mounts and trying to adjust the antenna pole. I think it would be a better product if they would just include the four extra nuts, so you don't have to run to the hardware store. Seems to be working well after a couple of months.

excellent quality.

I used these brackets to piggyback a GMRS antenna to our old TV mast, which also has a PWS on top. I don't recall the pipe diameter, but it would fit most common sizes I think.

I use these clamps to support a portable AM loop antenna, mounted to a heavy-duty speaker tripod. Perfectly suits application!

Connecting 2 pipes together for antenna works great

Very effective in connecting to poles together. They do weigh a bit though.
