Hooked up my SWR meter. 2m looks good (1.5:1) but the 70cm band is coming up as 3:1. I didn't receive any manual how do I tune only 70cm?

That is what the load in the middle is for. You need to loosen the set screw and move the shaft accordingly. You will have to monitor both frequencies to strike a balance between the two. Good luck

The SWR is a little higher on 70cm, but yours is a bit to high. What are you using as ground plane? is it mounted on a car.I have mine mounted on a metal pole with out a ground plane, the SWR is OK this way. You may want to try different ways and places to mount.

Try adjusting the length of the bottom rod for a better 70cm swr. It will effect the 2meter swr at the same time and you may have to adjust the top rod to to improve it. Carefully measure or mark the original lengths before you change anything so you can put it back if you need to.

First you need a SWR meter. The antenna tunes by the set screw and how far the whip is in the base. If you get a SWR meter it will have all the info on how to get the lowest setting possible. I bought the Workman but it dident come with the short antenna wire needed to set it. But once you have all the parts it's very simple. If you only have the one, it my be cost effective to find a CB shop. For a small price they will set it. Good luck hope I helped!

It will behave like it is working, but the SWR indicated will be off. Found this out the hard way.As stated elsewhere get the Nissei RS-40 for these measurements.

Check your manual. There is a setting for the tuning steps to be set. In some parts of the world the AM Broadcast band steps are 10 KHZ apart and other areas are 9 Khz. If you are in the USA it should be set for 10 Khz. There is also a filter setting that you might want to widen for better sounding AM. Does this help?

Not much at all! I have an external SWR meter but there is one built into the radio that I used to match the antenna. The radio was up & running in no time. I used a cigarette lighter plug to quickly connect the power. Talking in about 15 minutes..

I am a ham operator and have installed more auto antennas than I could count. This has a long whip, short whip looks to be just chopped for photo. Assume you are going to use a trunk lip mount that will require at least 1 of the mount screws to go to metal under lip of trunk. Should be able to get swr down to 1.5 to 1 depending on how close the whip is to metal. this antenna worked out just fine for me. Steve -WB9SNS

I currently have a 4' Astatic half-breed. I also use Firestik antennas. The Astatic has less static and better range. You can use a magnet mount but I dont know what vehicle you have or how you want to mount it. The #1 thing is to set the SWR for any antenna. Look it up if you dont know- you will need a meter or a cb shop can do it sheap. If the antenna isnt tuned the transmit circuit can burn out on you cb.

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.

To be truthful i wouldn't recomend this antenna becase it is hard to tune and i had problems with the glue on the outside part of the antenna if fell off after it got wet a number of times the transmit range is not that good .I would recomend a wilson 1000 magnet mount it will hook up to your midland radio miminal tuning with a swR meter to get a good swr and you radio will get out farther..just remember to tune the antenna on channel 21 set for lowest SWR 1.1 may have to cut the bottom of the whip a 1/4 of an inch and put the antenna all the way at bottom of antenna tighten set screw and see what your swr is you will need an swr meter most shops can check it for you good luck To be truthful i wouldn't recomend this antenna becase it is hard to tune and i had problems with the glue on the outside part of the antenna if fell off after it got wet a number of times the transmit range is not that good .I would recomend a wilson 1000 magnet mount it will hook up to your midland radio miminal tuning with a swR meter to get a good swr and you radio will get out farther..just remember to tune the antenna on channel 21 set for lowest SWR 1.1 may have to cut the bottom of the whip a 1/4 of an inch and put the antenna all the way at bottom of antenna tighten set screw and... » Read More To be truthful i wouldn't recomend this antenna becase it is hard to tune and i had problems with the glue on the outside part of the antenna if fell off after it got wet a number of times the transmit range is not that good .I would recomend a wilson 1000 magnet mount it will hook up to your midland radio miminal tuning with a swR meter to get a good swr and you radio will get out farther..just remember to tune the antenna on channel 21 set for lowest SWR 1.1 may have to cut the bottom of the whip a 1/4 of an inch and put the antenna all the way at bottom of antenna tighten set screw and see what your swr is you will need an swr meter most shops can check it for you good luck « Show Less

This antenna will work fine on 10 meters. Just trim to achieve lowest SWR in the middle of your expected operating range and enjoy ! !

What type of antenna are you using. On my midland magnetic mount it tuned to good SWR. On my Xterra with an antenna on the roof rack I had to add a thicker longer ground wire to the antenna mount.. SWR is related to the antenna more than the radio.

Really the only difference is the frequencies, (and the antenna is tuned for those frequencies). As to why, I bought the 2m/1.25m (144/220) because there is almost no activity in my area on the 70cm band (440) but there is a 1.25m repeater nearby that we (my wife is also a Ham, and also has a UV82x) can talk to each other on from just about anywhere in our area. So the one you want depends on the bands commonly used in your area. And in case you didn't know, this is a FCC Part 97 Ham Radio, as well as a Commercial FCC part 90 radio, both uses requires a FCC license to legally use. This radio is NOT part 95 legal (MURS and FRS/GMRS) Really the only difference is the frequencies, (and the antenna is tuned for those frequencies).

I don't know the answer to your problem, however I purchased the same antenna, and as far as I can tell it's like a dead short on every band which leads me to believe the coils are no good. I have tried adjusting it I have tried grounding it, nothing has worked, the SWR is off the charts and by the time I tried to use this antenna it had sat for over a month due to the severe winter weather and I could not get outside to mount it. Mine is useless.. I have checked the coax, etc, and I have a triband Comet 2m,440, 6 meter antenna that works and has a 1:2:1 almost everywhere on the bands I use it on.... So I know my setup is fine but that antenna is junk in my opinion...

It has two "SW" bands. SW1 Tunes 5.9-10.0 MHz (5900-10000 kHz). SW2 tunes 11.65-18.00 MHz (11650-18000 kHz).Reception in these bands will vary by frequency, time of day and season. If you web search "Shorwave Bands" you will get lots of info on when to use various frequencies for best results.

For transmitting (TX) - NO WAY, you will have a SWR that will burn the finals out in the non-CB radios.For receiving (RX) on the other bands - just about any antenna will work to -some- degree; the closer the band the antenna was designed for (in this case the 11 meter / 27 MHz band), the better.

No, it won't. You'll get SWR readings, but they won't be accurate for anything as high as 2 meters. This is a classic, old time CB SWR meter that's calibrated for 11 meters. If you're looking for 2m/70cm, check out the Nissei RS-40, available on Amazon. Works with up to 200 watts, and gives you reasonable accurate SWR/powers readings for both bands. If you only need an inexpensive SWR meter, I'd recommend this one.

First of all I am a ham radio operator and may have a better understanding of radio wave propagation. I say this because many people feel their radio is not receiving as well as it should be. At this time in the sun spot cycle the bands are not too good. 40 meters should give you some good activity late in the day and early evening. Now as far as your external antenna goes it will be best if it is resonant to the frequency you wish to receive. On my pl660 the lower frequencies respond better to the plug-in wire supplied with the radio. You can buy one of those tuned antennas that plug in. Go on youtube and put in degan w31ms.
