If you have any questions at SWR, please leave them in the comments.

@zacharyrodgers597 Год назад

Best comparison I’ve ever heard. Next time chief asks why the radio isn’t working I’m telling them it’s backed up

@Overlanding4Fun Год назад

You can tell Chief that the CHT tank is full and the radios are backed up because of it.

Great video Tim!

Glad you enjoyed it

@kevinwiss6011 Год назад

Good info! NOW, you should do a presentation on how and where you mounted YOUR radio and antenna on your Bronco!

@Overlanding4Fun Год назад

Coming soon! I am working on a video on how to measure SWR and another on what to look for when you mount an antenna and how it could effect performance. Around the 10 minute mark of this video, I show where my radio is mounted and a little later it shows were the control head is mounted on the dash. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HOnD94ASTLQ.html

Hi the swr are different on my radios swr meter and the external meter, when I connect the swr jumper the swr goes up. When I disconnect it the swr go down. How can I get to read the true swr? If I get a radio without built in swr it would be be fried because of this mismatches.

@Overlanding4Fun Год назад

The most important place to take the SWR reading is at the point where the RF signal leaves the radio and enters the antenna feed line (coax). This can be achieved by an internal meter or external meter and there might be some variation between the readings of the two meters. The difference between a 1.5:1 versus 2.0:1 might be minimal or significant depending on how much power you are using. If you are using GMRS with a minimum of 50 watts, that difference is negligible, but with Amateur Radio at a maximum of 1500 watts that could be significant. If you are seeing a significant jump in the SWR reading when you insert an external meter and jumper between the radio and the antenna, it could be an indication that there is a problem with the external meter or the jumper. For example, it can be possible that the connectors on the end of the jumper has a bad connection to the center or shield of the coax and is introducing more impedance to the feed line. This would cause the SWR to increase. I hope this helps. -Tim

Can anybody help? I’ve got my cb antenna setup and my swr 2.5 on ch 1 and 3.0 on ch 40 ….everything’s new how can I lower my starting swr? I know about lengthening and shortening but is there some way to get it to a lower starting point? Should I add a spring? The antenna is a 7 foot firestik…I just don’t know why my starting swr is so high

I know with 10 meter mobile antennas, similar frequency range to the 11 meter/ CB, it is important to make sure that the antenna base is electrically grounded to the body/frame of the vehicle.
