A simple solution that could make your life so much easier. If you ever wanted to mount a N or SO239 connector to your enclosure and connect coaxial cable to it in a clean and effective way without adding parasitic inductance and making it all look like a mess, you probably noticed that this isn't so easy to do. We do have a simple solution, however. This small PCB screws tightly and directly to the N or SO239 connector (see pictures) and enables a clean, electrically excellent and also good looking contact. To top it off, it also contains a small stripline directional coupler. Three-pin solder header provides ground and two voltages, one for SWR and the other for POWER. You can now measure this voltage to determine your output POWER or SWR. It is also possible to use this board to simply build SWR protection.
Coaxial cable can be easily soldered to the terminals as shown on the photos. We recommend teflon based coaxial cable for such interconnection wiring since teflon isolation does not melt when soldered or heated due to high power level. Boards with installed 15cm of RG142 teflon cable are also available. This cable is also prepared for soldering on its free end, making installation extremely simple.
The boards are now produced on TEFLON laminate and take much higher power, also they are freqency compensated so a reading at 108MHz and 88MHz produces the same readings.
- Size: 62mmx29mm, PTFE (TEFLON) laminate
- Power handling: 0-1500W with heatsinking, above 1KW we recommend 1-2mm thick CuAg wire across middle conductor for safety.
- Frequency range: 0-500MHz (Frequency compensated for equal reading inside entire FM broadcasting band)
- Connectors supported: N and SO239
- Includes: PCB and all components, connector and screws not included
