1. The JHLA-6BP Lighting Arrestors are designed toprotect equipment from surge caused by lighting strikes on tower or in closeproximity to antennas. Lightning strikes are typically pulsed DC but there isalso an RF component at about 2.2MHz. The first pulse averages 18KA. Subsequentpulses are usually about half that. An average lightning strike consists of 3-4pulses. 2. Proper grounding of the antenna systems and towerare imperative to prevent equipment damage. Antenna and equipment should beconnected to a single point ground. The best ground is a 3Ft or longer cropperrod driven into the soil. Alternate grounds are (in order of decreasingeffectiveness): ●Building Steel or rebar ●Cold Water Pipe ●Meter Building Skin ●Electrical System Ground 3. Pole and tower grounding should utilize copperbraid or strapping for maximum energy dispersion. 4. Coax cable should be grounded at the antenna andwhere the cable leaves the tower or mounting pole. If the antenna mounting poleis properly grounded, then the antenna and coax are grounded via the antennamounting bracket system. The coax should also be grounded as low as possiblewhere the cable leaves the tower or mounting pole. Grounding kits are readilyavailable to ground the coax to a tower base or pole base. 5. The JHLA-6BP comes in a 230V discharge model. Thedischarge voltage is the threshold voltage at which the surge suppressor startsto dump energy to ground. 6. The JHLA-6BP Lighting Arrestor should be locatedas close to the radio equipment as possible. 7. Ground the JHLA-6BP Lighting Arrestor by using anAWG#8 wire and crimping or soldering to the wire lug included on the JHLA-6BP.You can also use a larger wire (#6) and wrapping around the grounding screw. Theother side of the wire should be connected to a solid earth ground. A solidearth ground can be a properly grounded tower or mounting pole. The connectionpoint for the ground wire from the JHLA-6BP should always be closer to thesingle point earth ground used than the radio equipment grounding location.Another grounding method is to mount the JHLA-6BP to an enclosure, then thebulkhead N connector becomes the ground path. 8. Waterproof all connections using a goodwaterproofing tape such as a self annealing rubber tape. use an outer coating ofhigh quality vinyl electrical tape. Spiral wrap so overlaps act as shingles toshed the water. 9. If mounted in-line, support the lightning arrestorby tightly tie wrapping to the tower or pole using UV resistant (black) tiewraps. | |
