This stand allows you to keep the units together and when deployed in a compact format. I use this frame for POTA and is a great affordable option. The material is a chopped carbon fiber imbedded heavy duty nylon and is both incredibly strong and tough. It will preform flawlessly for years and uses matching stainless steel socket heads, which match both the TX-500 and the PA500.
*** please note: this is only for the frame. not the TX-500 or the PA500 ***
