I never picked up the lingo from CB, I always found it to sound cheesy. Remember, the signal at a repeater site doesn't just travel a few feet to an antenna like in a mobile rig. Using the above formula, cut the antenna a little longer than the calculations say. For example, if the tuning range of your tuner has a sufficient range, you will be able to load up any antenna with it, but it will not necessarily radiate a signal efficiently. A choke balun does this perfectly, without using any ferrite beads or toroids.
This specific model even has carry handles similar to a PRC77 and comes in OD if you want to pay extra. Such was a case not long ago, and we will discuss the outcome of that incident, but first let us talk building antennas. And the more isolation the better. One side of the antenna is the metal vertical radiator and the other side of the antenna is the earth ground. This causes extremely high losses, and very little power reaches the radiating part of the antenna. The various models of controllers have different useful features like speed-dial for phone patches, a voice clock, facilities to control a remote base or linking, etc.
In days of old, repeaters that used PL were considered to be closed or private. That means no SSB. Q: What do the words "manually" and "automatically" imply? Backscatter will confuse front-to-back measurements of directional beam antennas. This causes extremely high losses, and very little power reaches the radiating part of the antenna. It can be fed with ladder-line and a tuner and used as a multiband antenna, or it can be fed with a quarter-wave-matching stub with ohm coax cable to make it a single band array.

I was very disappointed to learn when I did move into Amateur Radio that some of the same behavior exits. It requires a large area of land, and also it can be fed either in the middle, or an end portion of the loop.
At the ends, strip the insulation back several inches, Twist the bare wires together, solder them, and run them through insulators. The extra wire can be let out to make it resonate on a lower frequency. Amplified RF also hurts worse, due to the added power applied to the antenna.
If you have your radio tuned to Splice the speaker wire onto the 2 ends of the IMT to connect the antenna. Having all those numbers written down ahead of time and programmed into your phone 101 questions & answers about CB antennas.
book make the difference between help and a busy signal. On many occasions, we have worked stations far away across the equator in the southern part of South America and stations in between could not be heard.

book frequency until you reach the infrared light waves. Moreover, if complaints are received that your station is causing disruption to other operations, your STA may be terminated at the FCC's discretion.
Antenna Impedance Technically, antenna impedance is the ratio at any given point in the antenna of voltage to current at that point. To reiterate, the extremely high capacitive reactance may make it impossible for its reactance to be tuned out and reactance prevents a transmitter from delivering power to the antenna.
Since one term is positive and the other term is negative, you subtract smaller value from the larger. Double Bazooka Dipole 6. Hard lines are cut or destroyed. Those are the ones we will be talking about here in this article.
What is Doubling? So why do we use it? Since the height of the ionosphere varies, the higher the ionized layer becomes, the farther the skip will be. This will allow you to hear AM and Shortwave broadcasts.
This stub provides a degree phase shift so that all half-wave segments are fed in phase. Having the ability to make contacts on a particular antenna doesnt mean it works well!
To make a long story short, the duplexer separates and isolates the incoming signal from the outgoing and vice versa. Amateur radio satellites in space. Height, length, feedline, balun, and we will talk about a balun laterinsulators, type wire used, or type metal used, what do you want to do with this antenna, how many bands do you want it to perform its work, if you can use the right materials, space to hang one, and the biggest of all downfalls, if you live in a place that has zoning laws, you may have to get permission gag to put up an antenna on your own property!
In this book, we will use the dipole as a standard for the most part. Calculating the Length of a Half-Wave Resonant Dipole The approximate length in feet of a half-wave resonant dipole is found by dividing by the frequency in MHz.
If the system has a tuner, part of the power is lost in the inductor of the tuner and part is lost in the feed-line.This page displays the Gallery of Books/Manuals for sale at the Radio Attic.
