Print in something strong. I used PRILINE Carbon Fiber Polycarbonate (PC), available here: https://www.amazon.com/gp/product/B074DS3986/ To assemble this, you will need: * 4x M4x16mm button head screws * 4x M4 nuts * 4x M4 washers * A shorter 3.5mm control cable, like this one: https://www.amazon.com/gp/product/B072TYZ89H/ * A short right-angle BNC jumper, like this one: https://www.amazon.com/gp/product/B07YFCXNR1/ Assembly is pretty easy: 1. You can either run the control cable through the little cable run on the bottom of the mAT-705Plus case first (depending on the size of the connectors on your cable) or run it around the back later. At any rate, it's best to test this now before you fully assemble it. 2. Run the screws through the holes in the top of the base IC-705 case and through the holes in the bottom of mAT-705Plus case. 3. Place a washer on each. 4. Tighten a nut down onto each screw from the top. 5. Connect the BNC jumper from the IC-705 antenna port to the mAT-705Plus's RF IN port. 6. Connect the control cable from the IC-705 Tuner jack to the mAT-705Plus's CON port. 7. Connect your antenna to the mAT-705Plus's ANT port. 8. Configure the IC-705's tuner jack protocol (Menu->Set->Function->Tuner->Tuner Select) to "Others". 9. Operate in compliance with your license.
