Tip: K9AY/4-way controller

It is a universal driver for 4 RX directional antennas. You can control the antenna directions with a DC voltage or you can use an internal crossover (Bias Tee) and supply AC/DC voltage along the coaxial cable of the RX antenna. Jumpers inside allow you to set the correct voltage combinations. Entry protections are available, HPF to block AC noise, three bandpass filters, preamplifier and RX direction switch. Thanks to this switch you can use RX antennas with any TRX – you don't need the RX ANT IN connector on your TCVR. The Rload controller changes the DC voltage from approx 6 do 1,5 V and you can use it with K9AY for example and change the loop termination resistance. The REMOTE version also has the option to control these functions with an external controller.

Tip: PL-239 professional connector

It is a professional connector for ½" coaxial cable with impedance 50 ohms. This version is available for a flexible cable as well as a classic ½ coaxial cable https://hamparts.shop/connector-pl-239-male-to-12-classic.html

Tip: RX Triplexer 2L

In this RX Triplexer 2L, three bandpass filters are used as a splitter or combiner with very low noise and very good bandpass filtering. You can use it as a single-band signal combiner or as a multi-band antenna splitter.

Example of use:

• One antenna to multiple single-band RX
• Multiple antennas to one multi-band RX (or several)
• for SDR web skimmer, CW/RTTY/FT pre RBN
