Uniden PC 78 XL
Old Cobra 29 LTD (Stay away from "Sound Tracker" Models, Look for ones made in the Phillipines, or Maylasia, The Japan models are junk)
Galaxy 949/959 These are great radios, hands down the best on the market right now, however they are pricey.
Tuning an ANTENNA, You cannot Tune the radio (Well it can be done, but YOU cannot do it)
Hook up your SWR meter between the radio and the antenna
Radio>SWR Meter>Antenna
Actually take the time to read the instruction manual for the SWR meter.
One thing to remember here is that the SWR meter, is just that, a meter, It does not adjust the SWR.
Take a reading, if its above 1.8:1 you need to try a few things. Adjusting a SWR can be extremely aggrevating at times. Try to raise the antenna 1 1/16" check the meter again. If the SWR is higher than before, you need to lower the antenna, if its lower, try again.
Repeat this until SWR is lowest possible.
Once the SWR is as low as possible, disconnect the meter, and reconnect the radio
Radio>Antenna.
SOme meters can be left in-line permantly, however, every connection causes a little lose in your power, so I would disconnect it.
Some radios have a built-in SWR meter. These are usually very unaccurate, and are not to be trusted.
An SWR of above 2:1 is too high, and you could harm your radio.
If theres any more questions just let me know. CBing is a hobby of mine, so Ive got a bit of knowledge here.
