All the two way communication devices I have seen give ranges that are at
best optimistic and then at only best possible conditions. The more power
the device has [all else being equal] the better your range though going
from 1 watt to 2 watts will not come close to doubling your range. I would
also look at devices that have multiple power levels because you want to
conserve power when you do not need full output. Having backup devices is
always better then nothing. Keep in mind that the type of communications
these devices use is "line of sight". If there is a hill between the two of
you range will be poor. If one person is much higher than the other and the
path is relatively clear the range can be very good. I have a modest
vertical antenna on top of my house at 35 feet above the ground for 146 mhz
and with it my range is over ten miles to other users on the ground and up
to about 50 miles for users with similar antenna set up. Directional "beam"
antennas can extend range dramatically [well over 100 miles] to other beam
antennas pointed at each other. With the built in antenna for my HT about a
mile is good for HT to HT communications at ground level.
So if you need to use a HT device try to get as high and in the clear as
possible or consider an outside antenna. I don't know if they make external
antenna devices for the consumer devices though one could be easily built if
need be. Even one in the attic of a house could extend the range quite a
bit. Otherwise consider getting your ham license. You do not need to learn
Morse code for the entrance license and the exam is fairly easy with books
that have the questions and answers. With a ham license you could then also
purchase higher powered FM mobile devices for your cars. Event without a
repeater with car to car using 50 watts FM your range should be at least a
couple miles due to the combination of higher power and a much better
antenna that would be used on the car. A car mobile possibly would also be
able to communicate with a HT on the ground within the range you need. A new
FM mobile radio can be purchased for well under $200 and there are
economical mag mount antennas that can be stored in the trunk until needed.
These antennas can be as little as a foot high. Good luck. --- Steve
