When the SHTF what would be the point to point communications routine. I am going to assume HAM. Won't be able to rely on cellular phones, Dial up, or internet. @ cans and a string won't go very far, so....
Assuming it is HAM, I have a few questions.

Eliminate repeaters that are currently in existance as batterries will eventually go dead. What band is going to be best?

What radio manufacturer seems to make the best equipment?

Are there models that are fairly portable that cover more than one band, or is a seperate unit required for each band?

Since someone will eventually setup a repeater in the aftermath what would the most likely choice of bands be?

What band in the most portabel size unit allows for the longest distance communictions?

I have noticed that marine band radios usually have higher wattage output, is this a fair alternative?

Thanks
