[QUOTE="Family_Dog, post: 967270, member: 82"] Some more feedback on a J-Pole antenna... Last week we had a VHF Repeater struck by lightning, the repeater survived thanks to the Duplexer that is used but the 3dB Collinear antenna was zapped by lightning and literally exploded into 100s of little pieces. As we did not have a low-split VHF antenna in stock (these are fairly frequency-conscious) my business partner built a J-Pole VHF transmitting antenna (?142MHz) and we installed it at the client's farm. The farmer has since reported that he is now able to communicate in places in which previously they had no radio comms and he is very happy with the antenna. No photo unfortunately, but an added advantage of the J-Pole antenna is that it is DC-grounded to the 30M Metal mast, which provides added lightning protection. -F_D [/QUOTE]
