The first place to look when you can only get out no more than two miles is your ground plane. To check this, use a multimeter and do an resistance check between the antenna mount and multiple points on your vehicle. This is a common problem on mobile units.

Tip

Cb ranges in mileage.


I have experimented for many years with various antennas and gain in the frequencies 26.965 to 27.405mhz. I have found that best performances on the Citizens Band is upper channels 37 or 39. This is where the band gets quieter and more close to Fm type communicating. Performance in antenna and hearing is best here. The Antron A99 sitting just 15 feet will get you 50 miles with decent results on a cheap Cobra 19plus or Cobra 21LTD. I can tell you by fact that a Cobra 21Ltd is equal to Cobra 25Ltd's(don't let noone tell you different) Its the same board, same calibration, same wattage plus its about $15 or so dollars cheaper than. Antennas have to be set for your frequency. I have found that the 8.5 ft(102 inch) steel whip performs best at approximate Channel #37 to 40. Homemade antennas built with a 8.25 ft element and 2 8foot rods down the side(ground) with a rod crossing the bottom at 1.5 feet. In the shape of a womans skirt.( Do not let the ground "skirt" touch the pole,seperate it by plastic PVC or milk jug with trash bag ties) I got 50 to 60 miles with this homemade job I would say had a DB gain of 10dbi. I have built home antennas that outperform Antrons. To be safe though and quick to setup is Antron A99 for about $65. Antrons have already set the frequency and low SWR. !!!DO NOT TUNE ANTRON A99 - IT BREAKS INTERNALLY!!! The average range one can get is say 10 to 50 miles average(best at night 10pm to 3 am) Don't expect any better with a Superior radio and tower or linear. A linear may kick hard within 25 miles but after that it fades into low in the distance. Unless you use 10 kilowatt or 25 Kilowatts(Electric bill will increase by $300 more--who needs it) A good power Mic on a straight radio Cobra 21LTD or 25 Ltd will be better than any mid-size linear say up to 250 watts. Your radio itself has potential with antenna gain of equal 25 to 45 watts alone. Mathematically your best with a Super Antenna and Height above 35 feet, plus heavy grounding(chain link fence buried into earth 20 X 20 feet about 8 feet down(a rod 8ft also will work) or if possible a Junk car buried into earth 8-10 feet under your Antenna. Use heavy gauge thick LOWLOSS 50 ohm coax 95% shield less than 100 feet to achieve max power out. Lengths in coax are great at 9,18,27,36 up to 72 feet(No higher than needed) The old timers swear by 72 feet. Antenna Height say: 45 feet tower with 72 feet of Coax is the usual Base setup. FCC restricts antenna towers to 60 feet above ground. No more than 20 feet above your house somewhat(when attached to house roof). No need to put $10,000 dollars in a setup with no more range than others. A mobile radio(Tuned) with Antron A99 will about outdo all Base station radios. Hope this helps you. 73's to you all.

I just bought a used cobra 200 gtl dx im totally clueless to cbs could u tell me where all the controls and buttons should be



  • Hi, I can help.

  • I have uploaded a pic of the Cobra 200 and labeled each knob/switch with letters to reference.
  1. A) Noise blanker - When this switch is pushed the high pitched noises are canceled leaving a more natural sounding receive. Some like it some don't.
  2. B) High Power - This button adjusts the power output of your radio. Inside the radio the pots are adjusted for a low power setting and a high power setting.
  3. C) Roger Beep - This is a beep heard by the person you are chatting with at the end of your transmission.
  4. D) The 10+ KHz - This button when pushed jumps the frequency up 10 Kilohertz to help you better navigate frequencies.
  5. E) This is where you adjust how you are going to modulate. CW is for continuous wave or Morse Code. Unless you have a key don't worry about this setting. FM is for Frequency Modulation AKA the HAM bands. AM is for Amplitude Modulation. USB and LSB are for Upper Side Band and Lower Side Band respectively.
  6. F) is the band adjustment - Each band (A, B, C, D is a set of frequencies.
  7. G) is a dimmer and the SWR calibrate. To use the dimmer push the dim button in a rapid motion. To use the SWR calibrate side press and hold the dim/calibrate button and using the SWR knob on the right side of the radio (L).
  8. H) SWR/, S/RF - If this button is in the out position then your meter will swing as usual. Push the button in to measure SWR.
  9. I) is the volume and squelch. Volume is what is adjusted to how loud you want your speaker. Squelch you adjust to take out the unnecessary white noise.
  10. J) Mic Gain and RF gain - Mic Gain is how much gain you want to your mic. RF gain is how much of the receive you want to pick up.
  11. K) Is the fine and course adjustment that you clarify your frequencies with.
  12. L) You adjust the echo and the SWR with.
  13. M) is the channel selector.

V12 MRV-1507 or Xplod? Amplifier - XM-ZR1252 good quality sound


Alpine is just a better brand in general. I have the older MRV-1507, sounds GREAT, i have had friends who has had the Explode line, but it was always a temporary system until they got something better, like the alpine or kenwood.

Cobra 200gtl High Power Transmit problem??


Depending on the type of power supply, radio frequency (RF) energy from the transmitter may be 'fooling" it into thinking that you're overloading it. Check to see if there's any discernible dimming of the meter lamp when this problem occurs, if so, the supply is the culprit.

Otherwise, its probable that the final amplifier transistors are overheating, either they are 'leaky' or not properly attached to the heat sink.

High swr ch. 1- 5 and ch. 40 - 5


This is a common problem in CB's. You can either get the radio tuned properly or tune the antenna. Sometimes the CB will put out more power on a channel than is needed and this could end up in a damaged radio. You can get the radio tuned to prevent the RADIO from high SWR, or you can tune the ANTENNA so tha antenna will better suit your CB's power.

Hope this helps!

No output


If you antenna SWR are way out ( too high ) you may have burrned the final or driver up when you hooked it up to do the antenna adjustment. Also be sure to turn the high power switch on to adjust the antenna SWR or the SWR meter won't read correctly, if the RF power is too low. Good Luck
