[QUOTE="Simmo, post: 611670, member: 4105"] Mate, what you have inadvertantly done is created an inductive loop, or one winding of a transformer... Putting your phone in close proximity to this loop, forms the other half of the transformer... By arse or by class, the loops together allow the RF to pass to each other. So your big antenna up high, is now adding to the efficiency of the phones internal antenna. At these frequencies 'skip' is non existent. Skip on HF is very common. On VHF, with tropospheric ducting, can get great distances. With UHF/SHF moon bounce comms is possible, but extremely hard to achieve. [/QUOTE]
