Modular Antenna switch

12x4 modular Antenna switch KIT - scalable on your terms

Can be controlled by:

Always used one same - three to one - module.
Put together up to four module expand up to 12 inputs.
Available add same module to next layer for next outputs (more second outputs).
Additionally expandable at a later time.
Using antenna output shows the LEDs.
Controled by grounded input (default), or high polarity (if soldered reverse all diode).
Power voltage 12V typicaly, dependency to used relay.
One module PCB size 85x85mm.
RF power loading
- 8A default PCB current (2,7 mm x 1oz)
- >16A with additional wire soldering
- 16A switching current
