Slinky Antenna
Electrically speaking your antenna is almost as important as your choice of radio, these slinky style antennas are pricy can be narrow minded, meaning they are only good for a specific range of frequencies....antennas that are narrow (banded) wont let you transmit freely wherever you want but limit you to a small area that the VSWR(standing wave ratio) is good for.
These groupings of frequencies are not only like personal preferences but are also respective to given geographics
(see watchmans short wave frequency list) 10 meter,6 meter, 2 meter bands. Another frequency limitation is, ceilings on wattage (power) all the way from 5 watts PEP (peak envelope power) to 100 watts PEP.
You need to be aware of what freqs you will want to transmit on and what freqs you will be happy to just be able to monitor.for information and survival purposes you will want to ideally be close to the 10 meter band. Choose a slinky with a low VSWR meaning, 1.5 or less, capable of high wattage meaning, at least 100 watts. And for goodness sake, get a lightning arrestor.
For survival purposes I operate in the high 27 MHZ on sideband and low 10 meter riding the fence and staying as legal as possible (low profile). I have a simple dipole with a clothesline style antenna for receive across all bands.
