Can anyone explain this?
Have a 5 metre pole antenna set up at our camp that has a fitting for the patch lead to take the old Telstra F165.
During a recent visit I coiled the end of the lead to act as a cradle on the shelf to hold my Samsung S5 in upright position. (Have on occasions previously received text messages with phone elevated and in vertical position)
Was amazed when a text message came through and later was able to make and receive phonecalls?
Is it just freak reception or could the coils wrapped around the phone be improving reception in a remote area?
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.
