Whether you are mobile or running a base there are three parts to the antenna system. The first part is the antenna itself. A good antenna should last you 10 years or more. Ultra violet light and moisture is the most common failure. The second part is the mounting hardware. This is subject to moisture and wind and should be checked periodically.

Only stainless steel bolts and mounting brackets should be used to minimize rust. The third part is the coaxial cable. This part of the system is the first to wear out; it is exposed to wind, rain and most importantly ultra violet light. If the coax is easily replaceable any good RG58 or RG8 coax less than 100 feet with 95% shielding will work.

If you never want to touch the coax again and you would like to bury it or not have it wear out, then you need to purchase RG213, it is expensive at $2 a foot but will last the lifetime of the antenna system. (more...)

In 1957 Congress authorized The Federal Communication Commission to create a citizen band radio service. The FCC or" UNCLE CHARLIE"
took the lower portion of the 10 meter amateur band and created a
very restrictive class "D" Citizens Band starting at 26.965 MHz, as
channel "1" and ending it with channel "23" at 27.255 MHz.

Except for channel 23 each channel was given a 5 kHz bandwidth with a 2.5 kHz bandguard on each end of the Bandwidth for a total of 10Khz between each channel or 10,000 Hz. (more...)
