This one really has me stumped. I have a CB radio in the 80 which is only really used on trips to Morocco but in the 10 years I have been going my transmission range has been absolute crap. My first setup was a Nissan Patrol Y60, Midland 78 CB and a springer antenna. Transmit range was <1 mile. This radio was then fitted to my second Patrol which was wrecked in Spain, but before being wrecked the transmit range could only get <1 mile again. Then in 2009 I bought the 80 and fitted the above radio to it but this time I fitted a Siro 3000 antenna which is supposed to be the dogs. Again transmit range was about 1 mile. Roll forward to this year and I decided to replace the radio and antenna. Radio is a Thunderpole T800 and antenna is a Mini Orbiter..... guess what the transmission range is still only about a mile. Tested it last night with a mate who was round and I could hear him about 4-5 miles away but he lost me in less than a mile. The antenna was on the front ARB but I have now moved that to the roof bars as one of the Tech guys at Thunderpole says it needs to be big up. I have even run an earthing cable from the antenna mount to the 80 body. WTF is going on, why can I only transmit 1 mile max in 3 different vehicles with 2 different setups. SWR is about 1 so that's fine too.
