I'm new to the cb world.so instead of going back and forth cutting my whip you can just match the signals to get the lowest swr and be safe?

As long as you have not dome something horriblely wrong YES this will work for you. I have used it for the same thing.

This is NOT going to "tune the antenna" - not at ALL. It will when properly set allow the transmitter to see a good "swr" and thus put out full (or nearly) power. The antenna will still be the same as before using this little gem; the swr will be as before but the transmitter will be as happy as a pig in poop. The ONLY way to "tune the antenna: is to actually TUNE THE ANTENNA! Period! End O' discussion.

Also, if your running high power it can make it swr hard to tune down. Make sure your coax is not coiled up anywhere. Make sure your coax is 18ft long and make sure you ground well it will make a huge difference. Good luck :)

Depends on where you tune the antenna. It's broad-banded, 27-28 Mhz 5/8th wave, which is physically 1/2 wave at 21-22.5 Mhz. Try twisting the tuning rings nearly all the way to the top. It should center tune around 28 Mhz and tune 1.5 swr up to 29 Mhz. Additionally, it should tune great near the middle or top of 20 meters (21-21.450 Mhz.) I installed the stock ground plane accessory and also cut four additional wire ground plane elements @ 1/4 wave of 21 Mhz (approx. 11 feet) Works great. However, you may not need the ground plane if you are less than 30 feet above ground.

If you have a tunable tip antenna go to FireStik.com and check out the TechDocs section. There are illustrations on correct continuity, as well as info on proper grounding and SWR testing. I was able to achieve 1.0 - 1.2 SWR on all channels on my Jeep with only half of the antenna above roofline. I originally had issues my setup due to incorrect grounding, and my SWR was in the red line as well. After fixing the ground I have near perfect SWR. The readings you're experiencing are more likely due to a short, bad ground, or coax issue before an issue with this radio/mobile transceiver. Also maybe try a "no ground plane" antenna if you don't want to deal with grounding. If you have a tunable tip antenna go to FireStik.com and check out the TechDocs section.

Yes I have done that. It works but remember the CB radio wave length works best when there is no obstruction. A straight shot to the other unit. Also, you only have about 5 miles before you loose contact with the other CB. It's not a cell phone by any means.

I don't know what is recommended but I use wilson antennas on all my cb's I have used a lot of different brands and have found the wilson's to be consistantly good. I have several different models I use depending on the car or truck or jeep. I use the 500 (lil wil) on the trucks, 1000 on the car and flex on the jeeps and buggies. I have used K40's and all 3 have lost connection inside the base ( had to cut them apart, sodier them and epoxy them back together. Most of the name brands are good and a good rule of thumb is the longer the better. and don't forget to set the swr's, (just my opinion I could be wrong)

I'm sorry I only use the SWR meter to align my Cb antenna, I'm sure you could Google the meter model, and find the answer.

You could try it, but insuspect you will get a high swr reading. This means that when tou try to transmit the signal will be heavily reflected back into your radio. This will severely limit your broadcast range and eventually burn up your radio. Mounting away from metal is best.

This is a CB tuner enabling U to fine tune in the signal....CB radios bounce signals from antenna to antenna...Ham signals work off repeaters which enable users to extend their range nationally and even globally....if U want a crisper signal then a tuner like this is great for a CB....

Yes. This radio is capable of picking up ham radio transmissions. For the antenna, I would suggest using the long wire that comes included with the radio instead of the whip antenna, or use your own wire antenna hookup (the longer the wire, the better). Also, I would suggest that you have some sort of amplified speaker attached to the headphone output jack. The volume output on this radio is not the best for copying SSB and CW transmissions and you will probably fare better using an external amplified speaker.

Yes. The "right out of the box" length might be perfect on one vehicle but a disaster on another. I had to snip about 3/8 of an inch off to get the SWRs down where they belong. Right out of the box, I was getting 2.2 to 2.5. After tuning and snipping, I now go from a high of 1.21 on channel 40 to a low of 1.02 from channels 20 down to 1. That's pretty respectable. I probably could get a more even curve if I snipped a little more, but these numbers are fine. On another vehicle, I might need more length. Use an SWR meter and do it right!

The first thing to know is that GMRS (General Mobile Radio Service) and CB (Citizen's Band radio) are not the same thing. GMRS is FM at 462 MHz and it's in most handheld radios now sold (usually 14 or 22 channels). CB, usually used in vehicles by truckers and others, is on 27 MHz AM and has 40 channels. SO you need to know which you really want. If you really want GMRS because you have other GMRS radios, the answer to the question is yes, it has 15 of the GMRS channels, BUT! it's not the best radio if you don't have a boat because it's so easy to transmit on the marine band by mistake during rugged outdoor use. That's illegal on land and can be very dangerous to boaters. GMRS-only radios are a better choice for that and most have 22 channels. And, frankly, this radio is a bit big and clunky on land and I have other GMRS radios I like better. Sadly, I can't recommend those because the ones I have are old and discontinued and hard they're hard to find used. If it's really CB you want, the answer is no, you have to buy a separate CB walkie-talkie. CB isn't often considered anymore for portable outdoor use but cell phones and cheap GMRS radios have emptied it out and the lower frequency can work better in forests than GMRS, and you don't need a license to transmit above 0.5 watts. For CB, I have a 4-watt Midland 75-822 and I like it.

A cb radio will transmit and receive with another radio that is on the same channel as you are, if you are within range and the other radio has transmit capability as well as receive. key the mike button on your radio to transmit let it up to receive that will do it good luck.

Check the SWR of the antenna for the frequencies that the radio transmits in with any of the antenna analyzers available on the market. If the SWR is not high, then the antenna is right for this radio. It makes no difference in operation what the ring around the threads states. It is the SWR that matters.

No. I've tried it with 10m and it has very flimsy build, and will arc at anything over CB regulation.

A lot of wrong information here. First of all, on the MT350R radio, channels 1-7 are allocated to shared FRS/GMRS use. Channels 8-14 are exclusively for FRS and 15-22 are exclusively for GMRS use. GMRS requires a license, though you wouldn't know that reading the Motorola documentation. This means, technically, channels 15-22 require a GMRS license to use legally. Channels 8-14 can be used by anyone. There is also confusion over the "power boost" feature. Again Motorola does not explain this well, and I'd guess is deliberately obscuring the facts. As near as I can tell the low power PTT is 0.5 watts and the high power is 2 watts. I couldn't find any direct documentation about this from motorola, but the numbers sound right. The point is, it is illegal to transmit on FRS above 0.5 watts. If you transmit using the "power boost" PTT on the shared FRS/GMRS or the GMRS channels you need a license. Summary: it is illegal for a non-licensed user to transmit on channels 15-22 under any circumstances (barring dire emergency). It is also illegal to use the "power boost" function without a license. Frankly these rules are a bit silly to say the least. And the FCC seems not to be too interested in enforcing them. With any luck the FCC will revise the rules at some point to better reflect the reality of the situation. In the mean time, if you want to break the law, fine. But at least you should *know* that you're doing so. As a practical matter, the best thing you can do to increase your range is not to mindlessly press the "power boost" button, but instead find a high place, like the top of the hill, and preferably some place with not too much in the way of obstructions. Your mileage will vary.

Not true. Although the SWR is generally close out of the box, each application will see different results. Highly recommended it is checked and adjusted accordingly.

If its for CB yes it needs to be tuned.sometimes you may have to much metal or not enough metal around it for a ground plane always check SWR's
