The area most sensitive to noise caused by corona discharge is at the very tips of a “dipole” style element. Unfortunately this is the highest impedance area, so the very high impedance RF noise caused by corona leakage is matched to the receiver system the best. The tips protrude into empty space away from everything else, and are often at or near the highest point in the antenna. This is where electric field gradient is strongest and corona most likely to form. HCJB was a high power shortwave broadcast station located at very high elevations in a humid environment. The environment at HCJB was one of the worst possible locations for a high power transmitting antenna.

In simple terms, your radio would like to radiate all of its power, but can only do so if the other components cooperate. Bad coax and mounts, or inefficient antennas and ground plane can cause system bottlenecks. The easiest way to understand the concept is to think of it in terms of water flow. That is, if you put a one inch faucet on a two inch pipe, your potential output will be restricted by the one inch outlet. So goes antenna systems.

Most CB shops sell dual antenna coaxial setups that are pre-cut and attached so all you need to do is hook it up. DON’T RIP OFF YOUR OTHER ANTENNA JUST YET. Before everyone takes this article as a negative blow to the dual antenna system – it’s good to remember that dual antennas can offer some gain in receive and transmit especially when using high quality antennas.

See the detail drawing on this page. Coat this connection with sealer or cover it with tape to protect it from corrosion. All vertical antennas need to be grounded in some way. A mobile CB antenna uses the car body as the ground. On this CB Antenna, the four radial wires are used as the ground. This is called the ground plane of the antenna. The braided wire which forms the outside conductor of the coax is soldered to all four radial wires. Remember that the inner conductor and outer braid of the coax must not touch each other, nor can the radials come in contact with the driven element.

Ah, the dual CB antenna installation! Few things compare in terms of the looks, bravado and downright classic rugged feel it gives to a pickup truck or big rig. But for pickup trucks especially, dual antenna installs are often chosen for the wrong reasons or with unrealistic range expectations.

Now, this radio doesn’t have a lot of bells and whistles that some of the other radios on the market have, but it is going to get you communicating on the CB band without breaking the bank. As for the installation, I am going to give this a simple two out of three wrenches. I say simple two out of three because there isn’t a whole lot to it, however, there is still going to be some wiring necessary. Now, as with any CB set up, you are still going to need an antenna and of course, you’re going to need the cable for the CB radio to connect everything up.

However, you are going to be able to get away very inexpensively with this setup and still have some communication. Some off-road parks will require you to have a CB radio in order in order to enter the park, other times it’s just a really nice feature to have when you’re cruising down the trail with your buddies, being able to speak with them very openly and easily.

Some parks, or any place, where you don’t have good cell phone reception, so there are a lot of reasons to want a CB radio in your Jeep. However, as with any electronics, there are those premium, top of the line, with all the bells and the whistles, and then the more basic and simple systems. And this is definitely a more basic, simple system that’s definitely going to save you some money over those premium systems, while still working really well to be able to get you communicating.

A big project and probably not practical starting out. Would make a conversation piece or odd recycling project. How are you going to point it? Smaller antennas may work just as well. Below is a stock picture Wikimedia of an old s style home satellite tv dish, about 8 to 15 feet across. That’s what you want to play with, if you have the time, energy, and patience.

Events Antenna Installation Guide: The antenna installation can mean that the antenna performs to its best or to its worst. By adopting a number of key rules and guidelines the best performance can be obtained from an antenna under any given situation. When installing an antenna, some compromises have to be made, but adopting some guidelines or hints and tips will enable the performance to be optimised for a given situation.

Some antennas may be domestic television antennas, others may be CB or ham radio antennas, whilst others could be for professional applications. Whatever the type of antenna there are many points to watch, things to think about, and items of good practice that ensure the best performance is obtained from the antenna. There are many different areas where thought needs to be placed into the antenna General antenna situation One of the most important aspects of setting up any radio antenna is its location.

The location of the antenna will govern many aspects of its operation, and therefore the location of the antenna must be determined along with the type of antenna to be used. A number of points associated with the antenna should be considered:

Outdoor Antenna

Where you install the CB itself is only important in regards to its ease of access and the orientation of the speaker so you can hear it. But overhead may not be an option and determining a mounting location is not always easy. If you are mounting under the dash or on either side of the center console, just make sure you have enough leg clearance. There are many companies making CB mounting mounting brackets, some of which are vehicle specific for some trick installation locations.

Mic Brackets — Most sets come with a mic mounting bracket that often can be attached to the side of the CB itself.

A citizens band or CB Radio is a short range 2 way radio used to communicate with other cb radios. They’re useful for communication between multiple vehicles traveling off-road together.

Tree Dents Here is my contribution to the leaking Transfer case Mine was getting soaked on both sides I was going to add fluid last night to buy some time till I could tear into it, and realized this was a walk in the park and I could have it fixed in not much more than an hour I made my own gaskets out of fel-pro brand gasket paper. It came from Advance auto if I remember right. Basically you just lay the old gasket on it, trace it then cut it out with scissors or an x-acto knife.

If you have a single hole hole punch it makes it a lot easier on the bolt hole area. I could not find mine last night, and didn’t wanna lose time looking for it.

Most of the veteran truck drivers at work have used the Cobra 29 Classic for over 20 years. Here is my problem: This radio is giant.

Aug 31,  · To adjust the swr you first run a single coax to one antenna, set it to as close to as you can, then move the coax to the other antenna, do the same, now hook up the phasing harness and check, you should be right close to , leave it alone after that.

CB radios have long been a mainstay for truckers, but they’re also popular with off-roaders, RV owners, and motorcyclists and hobbyists. CBs are useful in keeping groups of individuals organized and in contact during events, such as those enjoyed by “wheelers. Also, some drivers still use CBs to identify speed traps, even though radar detectors have largely taken over that task. Using your CB could help you find an alternate route in a traffic jam, warn you of road blockages ahead, get you real-time weather reports and severe weather warnings, and get you assistance for a mechanical breakdown or medical emergency.

On long solo trips, the CB can be the faithful companion that keeps your interest, making the miles fly by, while also helping you stay awake and alert. Once you’ve decided to get a CB radio, selecting one that is within your budget, will meet your communication needs, and is suitable for your vehicle are preliminary steps that can affect the CB radio installation, set-up and hook-up.

Choosing a Radio In one way, all CB radios are the same, no matter what you pay: There are three general types of radios based on their intended use, including: For the all-in-handset radio, there are only two options. The popular 75wxst is the only true all-in-handset. Also, the Midland comes with a mobile adapter that allows it to be used as an all-in-handset radio.

How do you merge two antennas to one signal.

Orders requiring technical work are shipped in about days. It’s tuning can make you or break you. When checking the SWR or the “Standing Wave Ratio”, you will be hooking up a simple form of a directional watt meter between your antenna and the CB radio. The meter measures Forward power to the antenna system and then compares it to the reverse or reflected power from the antenna system.

By checking the SWR at channels 1 and 40 on your CB, you will have a good idea if the antenna is too “long” or too “short” for the center of the desired band. You will also be able to evaluate your system performance and troubleshoot problems.

After you’ve installed your CB radio, it’s time to add the antenna to the system. IMPORTANT: Do not key your mic before the antenna is installed! If you do, you risk damaging or destroying your radio! Selecting an antenna. You’ll find a great selection of antennas on our mobile antennas page.

Something that you can hide away and that still has a ton of functionality. So getting this installed is going to be an easy two out of three wrenches. I give it an easy two out of three because there is some wiring involved, but overall this is a fairly simple process. Now, this radio is going to be more expensive than some of the other ones on the market, but you are going to get a lot of additional features with this radio as far as functionality goes. And probably the biggest feature of this radio is that the whole brains of the operation is just this little small box here that you can mount anywhere you like, hide it out of the way.

And then when you want to be able to use your radio, all you need to do is attach the hand piece that has all of your controls on it, and also your speaker built right into it.
