ATTENTION: The price shown includes Greek VAT 24% and is applicable to all individuals in EU countries only. If you are from any other country including USA, Canada, Australia etc. please use the "make offer" button and divide the price by 1,24.We will first accept this offer to let you proceed with the check-out and payment. If you are a business registered in EU with a valid VAT number again, you can use the same button so to pay without VAT. We will send you a zero VAT tax invoice.

ORDERING: Both complete, encased & tested and PCB modules without enclosure and connectors are available. Choose the variation you need.

Attention: If you want manual control you will need to make a small box with a toggle or rotary switch to send 3.3 or 5V to S1 or to S2 relay select inputs. We offer a similar control box separately.

This is a high-power RF switch with remote control input, made with minimum-losses relays and it can be used to switch between 2 different antenna systems for a transceiver, or between 2 different radio transceivers for a single antenna system. 

Indicators: 3 mm green LED indicator to show which port is connected

Relay drivers on-board, it can be controlled by any GPIO, output pin of any microcontroller, Arduino, Pi, ESP-32, Bluetooth device or Wifi or GSM/4G/5G switch for remote applications.

Connections: S1 and S2 input pins if get a HIGH (3.3V or 5V) will energize the corresponding relay. Deactivation is done by stopping the application of the input signal. G is the Ground (0V) connection and + is the plus connection of the 12VDC power supply.

DC Power: 12VDC, 40 mA - If the unit is not powered with DC power or no inputs selected, the relays connect the RF ports to Ground

Dimensions: 111 x 67 x 37 mm die-cast Aluminum Box painted Grey (98 x 52 mm for the PCB module)

RF Power handling: 1500 W - Not suitable for "hot switching", i.e., stop transmitting, then switch.

Insertion loss up to 70 MHZ: < 0.1 dB

Insertion loss at 145 MHZ: <0.12 dB

Isolation between ports: > 50 dB @ <30 MHZ  - Decreases at higher frequencies

RF Connectors: SO-239 (N-type on special order)
