    Asked by JPierce 4 years ago

    Question: Gas fuses act as a "diverter" and only have continuity once the gas is hit with several hundred volts(or more), so it cannot be checked with a standard Ohm meter. How do you know when the fuse cartridge needs replaced? 

    Answer: Thank you for reaching out to us! Often times if the cartridge inside needs replaced you may notice a decrease in signal, but the cartridge will usually appear black in color or damaged. For additional questions, please feel free to reach out to us here through our online help center:

    Asked by Jimmy 4 years ago

    Question: Will I need a short length of LMR 400 cable to connect this to my 471104 or can I install it without anything extra?

    Answer: Thank you for the question. We do recommend using a 2 ft jumper of cable between the antenna and surge protector - 952302:

    Asked by donw 5 years ago

    Question: I wanted to find directions for installation for the surge protector. I assume the ring termal is for a ground wire. I didn't know if we needed to install a ground rod to run it to or what the proper procedure was.

    Answer: There is a terminal at the top of the protector for inserting the grounding wire. We do not have any written material on how to install, only because we always recommend talking to your county electrician on proper grounding procedures. Each area can have different grounding requirements. We typically recommend 10 or 12 gauge copper wire.
