Considerations when travelling to remote locations. Find out all the interesting and fun things you can do when you combine a love of radio with a love of overlanding.
If the presenter had actually covered antennas - it would have been a better use of time. OK for very, very new/non-technical hams.
Anything more specifically you'd like to know about antennas? Everyones needs are very different. We use a Diamond HF30CL for APRS as we don't need to change bands often on that radio and a Codan 9350 auto tuning antenna for our general purpose radio. For monopole antennas on cars you generally want center or top loaded antennas to improve efficiency and bond everything in the car to make a good ground plane (every panel, bull bar, frame to cab, exhaust)
For a presentation called Antenna-palooza, it was the one thing not covered - antennas. I see the occasional "Overlander" video, as brave people travel across the wilds of Utah or Arizona on BLM/Forest Service maintained roads in large, heavily modified 4X4 ($x$) trucks- only to see the same road traveled (on a different channel) by an old guy in a stock 1965 VW Transporter. You tube - all about the click$.... Not to be confused with these lunatics. (rock crawling) In OZ, Overlanding is a different matter altogether - I understand that..
Ah, the event is called antennapalooza. There are many other talks, some covering antennas, others not.
