The first 4O3A commercial amplifier. Continuous frequency coverage from 1 to 30MHz. Our TWIN topology provides guaranteed uptime through redundancy.If one out of the two RF modules fails for whatever reason, the amplifier will still remain on air uninterrupted, keeping half power through the second RF module. The damaged module can be hot swapped with a new one with absolutely no downtime.

The PG-M VHF 642 is a state-of-the art VHF linear power amplifier that covers 50MHz, 70MHz and 144MHz bands and provides 1000 W output power (PEP or continuous carrier) with less than 50W of drive.

The revolutionary TWIN topology offers ultimate flexibility for your radio station, transforming with a press of a button to match your desired configuration.
Combine the two modules into a single powerful amplifier, delivering 3500 watts of power in SO2R configuration.

An advanced engineering approach to tuner development has resulted in truly highest quality hardware and software solutions.

This product is obsolete. Station Genius is a powerful station controler for complex switching. It’s designed for ease of use, versatility and expandability.

Transform your traditional radio into a cutting edge one. This accessory reads the CAT/CI-V band data from your radio and packs it into TCP/IP (LAN), making it a network CAT/CI-V server. Your radio can then integrate with any Genius device without worries.

Height: 4U, Width: 19"

This interface will convert frequency data given from RS232 CAT or CI-V to BCD output. BCD output can be used to control Antenna Genius or any other BCD controlled device.

These high-power (4,500 W ICAS) Band Pass Filters are to be fitted on the output side of your linear amplifier, filtering out not only harmonics but also broadband noise from the PA.

The 4O3A High Power HF Triplexer System Enables A Single Triband 20m/15m/10m Antenna (typically a Yagi) Fed With A Single Coaxial Feedline,To Be Used By Three Stations Running 4.5 kW simultaneously.

In order to meet the different needs and various setups of big stations we decided to put flexibility in to the foreground of our design. Instead of designing a simple Quadriplexer with four fixed band outputs we designed our Combiner QPXC-8, as an addition to the existing Triplexer System.

Eight antennas to two radios high isolation antenna switch.

Manual Antenna Controller S8 is an accessory in use with Antenna Genius, Antenna Switch 8x2 or Splitter PS3000RX.

A high isolation 6 antenna to 1 radio outdoor switch, with built- in high power CMC transformer, that can be safely installed at the bottom of your tower.

High isolation A to B switch, need for some applications such as extension of the antenna matrix.

The A50 switch is used as the 50 Ohm load for open ports on the HFC3000 combiner to prevent tuning degradation.

Due to the popularity of our A/B switches we decided to make a super-switch containing 8 A/B switches in a single box.

Lightning problems - a thing of the past! Introducing the first ever fully automated radio station protector. Fully automated it monitors your station and grounds all your antennas safely in cases of thunderstorms and more.

Power splitter can be used for splitting power between one, two or three antennas/directions, or for combining two or three antennas.

1A2R switch is a RF and PTT router which routes one amplifier between two radios. Switching is based on the PTT signal using the first one wins principle.

With the new reversible switch, you can easily exchange your amplifier and antennas in use in between two radios.

A controller for the RS3000 switcher. It makes sure that the switching can not be engaged while one of the users is transmitting.
