AMATEUR RADIO RVers NET tomorrow night (SUNDAY) beginning at 9:30 pm ET on the Quadnet Array (Dstar, DMR, YSF).

Eric Udell, KN4MCE, will moderate: Powering your radios or your mobile shack. How do you do power your gear? Straight from your 12V house batteries? If you're using a power supply, is it usually inverter driven or from 'shore power'? Do you have any noise issues with your inverter or solar controller and if so, have you resolved them?
Share your setup and any tips with the group tomorrow night on the net when you “join the conversation.”

RV Antenna Ideas. I have been fooling around with various antennas for years. Recently, I purchased a couple of MFJ Ham Sticks on 20 & 40 meters. MFJ has a truckers style mirror mount that they have configured to make a dipole out of 2 Ham Sticks mounted on a vertical pole. I have used this at about 25 feet with surprising results. Not as good as most base station antennas but enough to have some fun. I recently purchased the MFJ Octopus which allows 4 bands of Ham Stick dipoles at the same time. I have not taken it to a campsite yet, it looks like a big umbrella frame, but it worked well at home when I tuned it.

I will report back later this month when we are in the RV at Grapevine Lake, Texas. 73, Dennis

To be effective verticals need 50 plus radials. The N3FJP website has an easy to understand article regarding verticals here: http://www.n3fjp.com/antennas/verticals.html

I use the deluxe Buddipole system. It is pricey, but, it works. They (Mastwerks) now have a new telescoping mast that goes to 10m (32 feet). Their standard deluxe goes to 18 feet.
