Hi all; 
        I have changed internet providers and now use my phone as a hotspot. Previously i used a Netgear nighthawk router for internet connection to the outside world. I was with Telstra ( and now out of it's 2 year contract ) with this router and now is not used. it is 100% working order and only needs a new sims card installed and away you go. Very good order and was only used a couple of times that i had this unit. It comes with it's charger and quick start owner's manual. Unsure of what it is worth. Let's know what you are willing to pay. I'm Based in Bracknell Tasmania. Will post for the small cost of postage

hi, did you use it in the younder at all. far away from civilisation. thanks

Olestiffs that is what the Telstra Nighthawk is designed for remote use, and have external aerial sockets
Best aerial for RV use is Blackhawk Marine 7dB dipole aerial. Need a cable and patch lead with TS9 plug for modem. Give you 2X to 3X coverage of a phone terrain dependent. If your phone supports VoWifi and have no reception on the phone switch on the WiFi and you can make phone calls and SMS through the Nighthawk on your normal phone number.
If you want maximum reception need to be connected to Telstra or Boost, which is the Telstra Retail network. The Telstra resellers like Aldi, Woolworths, etc will only give you around half the coverage in rural areas.
