Whether you are planning a trip into the Australian outback, towing a caravan on back top or a weekend 4WD adventurer, then a UHF Radio is an essential communications tool to have. UHF (477MHz) radios have nearly replaced the older 27MHz CBs, mainly due to their considerable price drop over the past decade and the extended range offer by repeaters located throughout Australia.
UHF CBs use Frequency Modulation (FM) to transmit/receive. Since UHF signals generally travel in a straight line, the terrain impact how well the signal is transmitted or received. For example, UHF CB radios will perform poorly in hilly or forested areas and perform well in flat open countryside. UHF CBs can also access repeater stations that re-transmit the signals on another channel which can provide much further coverage (see Repeaters for more information).
Top 10 Sat Phone Tech TIPS Provided by MGLSAT
1. Getting Connected
TIP: Only open
the antenna outside, after you have turned it on and can see the blue screen.
Always be outside with a clear view to the sky and as much of the blue stuff as
you can get. Stay clear of objects like towers etc that may block and interfere
with the signal getting to the satellite. After all its 37,000 km's away so
give the signal the best change possible by being patient and clear of objects.
Again, only open the antenna after you have a fixed standing position and the
handset is powered up and the screen message is "deploy antenna for use".
2. Staying Connected
TIP: Keep clear of objects and with the antenna pointed towards the satellite (look for white bars on screen) and keep it pointed towards it, DONT WALK AND TALK! The satellite cant move so give it the best chance to see your antenna by staying fixed in a single spot.
3. Checking Prepaid Airtime Balances
TIP: Its free to check your balance, make sure you are outside, a clear view of the sky and connected and "ready for use" on screen. Go to MENU-TOOLS-PREPAY-BALANCE ENQUIRY Make sure you do this before you set off on your trip. Allow time for airtime to be applied if you purchased some
4. Buying Airtime On-Line
TIP: Before you head off, go to www.mglsat.com and buy some airtime to keep you and your family covered. Always allow more airtime than you will need. Better to have and not need, than need and not have!! Allow 24-48 Hours beforehand for airtime application to the SIM card.
5. Emergency Services 000
TIP: Before travelling look up on the internet for some local emergency contacts in the locations you are heading to and save the direct numbers for these into your phones contacts. 000 wont be much help in the middle of the outback so ensure you have the Royal Flying Doctors numbers loaded. See www.mglsat.com for details.
