Re: CB/SSB Radio Use - I have a few questions.
Galaxy is an excellent radio also you may want to think about the possibility of a tube radio and linear such as Yasu or Palomar Siltronix just make sure that clarifier is unlocked and have a frequency counter so as you and the people you wish to talk with can slide in between channels and also make some type of code amongst yourselves. A ground plane or an omni directional antenna may be out of business as the signals may be blocked by who or what. A beam directional antenna may be the way to go but hard to conceal. 10 meter will give you the farthest range without needing a repeater tower which will probably no longer be working. A regular cb with upper and lower channels and an unlocked clarifier would be the cheapest route. You dont need a lot of power to talk any type of distance you can use modulation to drive the signal. If its distance youre looking to talk then a beam antenna or a full wave antenna diapole with no coil so you can drive that linear as hard as you want. So many different scenerios which may keep any of them from working but it is a thought. Or just for loacl use a set or FRS radios will do just fine providing the signals arent being blocked.
