JC-5s Automatic Antenna Tuner. 4Kwatt PEP

The JC-5 is at the moment again in production! We do have new print boards.

We only produce the JC-5s on pre-order. Mail us for more information. Delivery time is still a few weeks.

But we do have some JC-5s on stock.

JC-5s  was designed to cover the needs of high power professional use and increased reliability.  So, materials of the best in market were used, despite the high cost of some of them, due to their limited production!  At the pictures  you can take a look at the inside of the coupler. In the photos we can see mounted in a row the vacuum relays, by which the high voltage doorknob ceramic capacitors are selected.  We can also see the high voltage copper wiring above the p.c. board.  The reason we did not construct the high voltage paths on the board is that we don’t consider the p.c. board reliable enough for withstanding voltages of the order of 8 KV that may appear at the output of the coupler when λ/2 or short vertical antennas are used!
