[QUOTE="p238shooter, post: 2401431, member: 24583"] Any radio systems for personal communications including GMS, FRS, commercial 150mz or so radios, marine radios, ham 2m and higher frequency radios are basically line of sight. There is very little bending and scatter for "over the hill" communication. That is why most important stuff is up on a tower, to "see" further. Higher power for range and scattering helps, but might not be a cure all for all situations at those frequencies with varied terrain. I talked to South America and Italy this evening on a Ham radio on 14Khz, but it was on a pretty hefty radio and a substantial antenna. If the power goes down, a standard 12V car battery will only give me 4-6 hours of talk time without a recharge. [/QUOTE]
