An AMRF junction box is a system specifically designed to allow the free flow of radio frequency in a hazardous location. Although most radio frequency installations are not done in hazardous locations, In cases where they are, an AM RF Junction Box will come in handy. Today, there are so many junction box models that help technicians prevent the potential problems of occupational hazards in a transmission facility.
With a very good Junction Box, you can make Antenna connections alongside HWA/HWS series. Another good thing about this tool is they you don’t need to install any kind of Ex rated HAZ or LOC input. Most AM RF Junction boxes are designed with low copper and aluminum that have anti-rust properties. This makes them very ideal for the harsh elements of extreme weather.
One of the best ways to connect an AM RF Junction Box is to join a large coaxial cable to the N Connector. The cable should have a spiral wound that connects the outer conductor. While you may not find this type of connector cable anymore, you can make use of an 8x8x4 cable to connect to your junction box.
Ensure the cable is passed through the electrical strain on the left side and am installed ground strap, which should be wrapped tightly around the conductor. Let the strap run through the station ground outside the box and all the way through the side of a copper strap.
Now run the cable conductor through the N connector to the right side of the copper strap, and you are good to go.
Another popular method is to rely solely on the Gap until the arc over is at normal power with full transmission modulation. Once it is at normal power, extend the distance of the gal by at least twice the distance. The type of setup is ideal for AM that are within the 530-1700 Khz range, not for FM within the 88-108 range.
