JC-5 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!
JC-5, Upgraded control Box, 2 pieces 4 pin connector, Manual and good packing.
You can also control the tuner with this control box. It is a very easy design so you can easy reproduce it to your own demand. You can also control it directly from many Kenwood and Icom transmitters
Price: TBD
Dear Sir,
IBBX (starup located in the city of Capivari – SP – Brazil) needs to purchase an automatic antenna tuner with the following specifications:
Frequency Range = 148 to 150 MHz (low VHF range);
Impedancia Antenna: 50 ohms
Impedance Range = 10 to 250 ohms (or more);
Withstand power = 30 W (p-p);
Power Supply = can be provided by the manufacturing company (if need);
Operation mode = automatic
Use of Female N or BNC conector (both sides);
More Detailed specifications will be made after technical discussion.
The tuner must operate together with the antenna and provide automatic adjustment of the antenna over the all frequency range specified above. Should be tune in to different types of antennas, such as: vertical antennas, yagis, or any other antenna with use by coaxial cable. The tuner that IBBX is looking for will not be used in conjunction with Communications Radios.
If the company does not manufacture this equipment or similar, please could you inform me who can do it
Thank you very much
Best Regards
