To clarfy my original point - Cradles with an antenna connection will provide a passive connection to a Mobile phone in the cradle - better than hand held ( especially better than the phone in the cupholder amongst the coffee thermos cups) The best performnce is when you have a phone that has an antenna connection that makes a metallic connection to the phone )( ie plugs in) - they will work where the passive ones do not. On flat ground there is around 12 - 15 km difference in coverage between a phone in a passive cradle vs one with a plug in antenna. ( yes i did the tests) The unfortunate fact is that the choice of phones with direct antenna connections is limited - Telstra / ZTE are the most common that have the direct antenna connection. so the compromise - is absolute coverage the goal ( with a more simple phone device) or is the smart phone capability with coverage not as good OK for your circumstance? After a recent 14 weeks bout the place ( and a ZTE phone with Cradle and direct antenna connection in the car) there were only a few places where i dug out the antenna and WiFi modem to get internet in because the smart phone (HTC)was not working effectively as a wireless hot spot. There were a number of places where it did not really matter as there was no coverage at all. But you expect that in the more remote places in the bush. of course there are antennas and there are antennas - that is again another topic altogether. If you purchase a "Blue Tick" phone from Telstra you will get access to the momre sensitive handsets (most without a plug in antenna) the question always remains - how important is the absolute max coverage vs the functionality of the phone itself. The Samsung is a very nice device.
