whats a decent small cb that i could get? and i've been confused about a few ppl talking about tuning in the antana, whats that about?
Eliminator89 said:Transmitting antennas must be tuned. If the antenna tuning is far enough off, it can damage the radio's output transisters. Someone almost always chimes in that they simply installed it and it works fine. Ok, perhaps they did. "Do you feel lucky...punk"?
As mentioned earlier, a meter is required. You can buy one for about $20-$30 or just get everything installed and have a local radio tech tune it for you. Having a meter is better because you can occasionally check it to be sure there has been no changes. As things age and weather, the tuning can change without your knowing it. Good to check it now and again.
Be careful about having the power turned up. You are stressing low power transisters to their limit. After a long winded transmission, feel the back of the radio. It'll be pretty warm. It should survive but be sure your antenna match is good.
A change of a couple watts just doesn't change your signal much. Generally speaking, a one S-unit increase on the receiver's meter requires a doubling of power from your transmitter. Going from 4 to 6 watts is not much of a change and could reduce the life of some pretty cheap power transisters. Better to properly mount a quality antenna. Have the CB checked for its power output and to be sure its on frequency. Cbs are mass produced by what is essentially slave labor. Best to have it checked out by a tech. Factory settings usually leave a bit to be desired.
