Zodiac R0441900 PDA Outdoor J-Box with Transmitter Replacement Kit for Zodiac Jandy AquaLink and AquaPalm PDA Control System

This is a very expensive part, but your system cannot be managed with the Jandy PDA if it does not function. I bought this part to replace a 12-year old original Jandy transmitter/antenna. I determined that the old one did not work by removing the front cover --- and I discovered that the two LEDs were not lit. The four wires from the transmitter run to a four terminal block inside your control box. You need a tiny screwdriver and tiny hands, but definitely a DIY job. From beginning to end, it took me 45 minutes.

does not fit the box even though it looks identical to my existing antenna, the wires and ground are different. now i have a very expensive piece of junk

Works fine after getting it installed correctly. But comes with no instructions - had to contact Zodiac to get instruction to pair it with PDA and where to place it important!).

WOrks fine, delivered ahead of schedule.
