The attachment linked below provides Pros and Cons to help you choose what you want to use. This is by no means all that there is to know about these different types of antennas, but it is a starting point to help you decide what would work best for you. I would invite all of the members to search the Internet and You Tube to gain more in depth information on each type of antenna.

There are a few considerations to make when operating portable and off grid. The attached presentation explores some of these things and hopefully will help you to understand some of the thoughts that go into the decision of choosing a way to power your portable station.

Some time ago I was asked by a new ham about how to install a mobile radio in his vehicle. My response to him was something like, do not use the cigarette lighter because the wiring and fuse to the cigarette lighter are, most likely, not designed to carry the load his transceiver will put on the circuit. I then suggested he run a separate circuit directly off the battery to avoid the problems that might arise by using the cigarette lighter socket. I suggested using a separate circuit for two good reasons. The first reason for powering his radio directly from the battery is that he can install and fuse a circuit designed to handle the current he will need for his radio. The other reason for running a separate circuit is that he can operate the radio without having to have the engine running.
