The velocity factor needs to be accounted for when determining the length of your coax. Antennas can be base-loaded, center-loaded, top-loaded or continuous-loaded. The next best location is to mount the antenna on the fender or trunk. Your radio signal moves through the air at somewhere around the speed of light, but it doesnt go through your coax at that speed. Content on this site may contain affiliate links. At the ½ wavelength there is what is called a zero voltage point.
Thanks for posting this helpful info. Continuous-Loaded — Continuous loaded antennas are very similar to top-loaded antennas in their construction with the exception of the wire distribution over the shaft. It has a stranded center, which makes it less likely than a solid center found on cheaper coax to snap when bent and pinched. This is where the signal is changing from a positive to negative or negative to a positive. If yours doesn't come with a mounting kit, get stainless steel or weather-coated metal antenna mounts. With a stranded center made up of many smaller carrier wires, you're much less likely to lose your signal.
Set it on one antenna then the other. However, most people don't want to drill holes in the center of their roof. If you don't have anyone available to you can look for additional information in our. While a properly tuned antenna will result in strong radio performance, failing to properly tune your antenna can result in poor performance and can even damage your radio from excessive radio frequency heat that is reflected back into the radio instead of transmitted out. Also, don't mount the radio behind objects such as the steering wheel that would block your view, or where it will be in the way of the driver, passengers or the movement of the seats or oops the gearshift. The old one had been adversely damaged by heat and moisture. Again, without this special cable your dual antenna setup simply won't work.
The manufacturers will tell you the velocity factor. There's a box to the left side of the driver's footwell in my truck I was hoping to tie into, but I haven't been able to get the cover off of it. It determines how much of the signal actually reaches the transceiver from. Note: My Tri-Mag antenna mount is already prewired with a Coax cable. This is how the cb shops came up with the 18 foot length of coax.
It may not seem very sexy, but coax is important stuff. For this, you might need to drill a hole into a wall of your home to pass the cable through. If I tune this thing does it matter if I remove it and return it to the set up in the morning? These cables have a heavier center conductor and an additional layer of shielding to better carry high frequencies with minimal loss. The audio quality of this setup is great. The decibel scale is logarithmic, so a loss of 3 Db is a 50% reduction in power.
Consider your cable routing when choosing your set mounting location. This is a great question, as the coax you select can make a dramatic difference on the performance and range of your antenna system. Most important, you'll have to be able to easily reach your radio's buttons safely while you're driving. There is good arguments to the 18 foot length. Nice and loud with a better than average speaker behind the dash.
Route the cable out of the way as good as possible. Keep in mind that when you mount your antenna on the edge or side of the vehicle a 360 degree radiating pattern will not be achieved. Screw down the terminal to secure the cables. Sounds complicated, but it really isn't. You can connect to any of the ports.
Examine your vehicle to determine the best location for the antenna to be mounted where it will have the most metal surface to radiate from. This way you can have your antenna properly adjusted, and your cb working like it should. The last time i heard is that you use 9 foot per side,not 18 ft. Tune the Antenna Tuning the antenna is one of the most important parts of the installation process. You could mount it under the car seat, but then you not only wouldn't be able to reach it easily - you couldn't even see what channel you're on or any of the other functions. Step 9 — Connect the Male End You need to connect the male end of the coaxial cable. If the mount was slightly thinner this would be avoided.
