This is very powerful device combines TRX switch, RX splitter, RF limiter protection for both RX outputs, INBAND RX antenna input and optional RX preamplifier. You can share your main TX/RX ANT to two RX with RF power limiter protection.

This is ideal solution for Spectrum Panadapter, WebSDR or Skimmer Server - RBN.

When the controller is OFF then main TX/RX antenna goes to the SDR RX output - with 10 mW RF limiter protection. You can switch ON preamplifier even you left controller OFF by the POWER switch. When the controller is ON, Main TX/RX antenna is shared between TRX and SDR outputs. During TXing, the SDR RX output can be connected to the internal dummy load or to the INBAND RX antenna input. You can switch the SDR RX output to the INBAND RX ANT port not only while the TRX is TXing, but by the front panel switch, it can be switched all time. Optional HIGH IP3 internal preamplifier can be used for insertion loss compensation. Additional gain is variable, up to 14 dB.

Main functions:

• Frequency range: 0,1 to 60 MHz
• Main TX/RX ANT splitter to two RX
• RX RF limiter protections for both RX outputs
• HPF (> 100kHz), high voltage and current protection at both RX outputs
• RX ANT (INBAND) input - works only for SDR output
• TX-RX switch controlled by the PTT
• Designed for 2nd RX, WEB-SDR, SKIMMER or Panadapter
• Controller OFF = TX/RX ANT port to SDR RX out via RF limiter protections - Skimmer/web-SDR
• Controller ON = TX/RX ANT port splitted to TRX and SDR RX out via RF limiter protections
• TRX TX to main TX/RX ANT = SDR RX out to dummy load or INBAND RX ANT input via RF limiter protections jumper switch
• Front panel Switch - SDR RX output to RX ANT (INBAND) during transmitting or all time
• Preamplifier (optional): insertion loss compensation, up to 14 dB of additional gain
• Preamplifier could be ON for SDR even the controller is OFF
• Very high isolation when TRX transmitting and SDR goes to RX ANT (INBAND) 100 dB @ 14 MHz and 80 dB @ 50 MHz

The K9AY is RX loop antenna terminated by the resistor. This is ONE direction antenna. There is no directional switching relay. Impedance matching transformer is connected from one end of the loop to the ground and load resistor is connected the other end of the loop to the ground. Favoring signals are arriving from the feed point end. You can set different values by the jumpers. There is also common-mode current choke. This antenna is designed for SO2R or M/M setup - you can share this one direction to the more RX

Main functions:

• Broadband 0,2 MHz to 30 MHz
• 1 direction about 90 deg.

The K9AY is terminated loop. It consists of a wire loop of any convenient shape (diamond, delta, etc), hung from a single support and with a ground rod at the bottom. A 9:1 impedance-matching transformer is connected from one end of the loop to the ground and terminating resistor is connected the other end of the loop to the ground. This antenna is directional. Favoring signals are arriving from the feed point end. There, with the two loops, you can switch between four directions. You can also change the antenna far field by changing the RLOAD (RTERM) of the loop.
