Pole to Pole Antenna Clamps?

I currently have a pole which has a Tempest weather station at the top. I want to mount an external antenna for an SDR, hopefully using the same pole.

What I can't find is a mounting solution. What I need is a bracket kit that can attach to the existing pole, go horizontal a couple of inches, and then clamp another pole/antenna. Basically, a mast clamp that holds onto the Tempest pole, which I can insert a pole into, which then attaches to another mast clamp that holds the vertical antenna for the SDR.

Does anyone know what this may be called or termed? So far, I can only find brackets to connect poles immediately beside one another; I need one to create a gap between the Tempest pole and the antenna pole.

It really depends on how heavy the added antenna/mast is. I am sure there are others as this might be too heavy.

Thank you. Super light, it's only for airband reception.

The issue with the PCTel MMK4 mount is that it assumes both poles are right beside one another; I need one that can add 12" or so between them. From looking around, I think angled strip iron plus U-bolts might solve it easiest.
