What is meant by co phasing?

Browse Encyclopedia Transmitting the same signal on multiple antennas. This is typically done to shape the radiation pattern in order to direct the energy in a specific direction.

What is a Cophase antenna?

First of all, co-phased antennas create a directional pattern that favors communications in front and in back of the vehicle. This is ideal for truckers and RV’s that use their radios to speak to those on the same road/highway that they are traveling on.

Why do trucks have two CB antennas?

On average, dual CB antennas are a better choice for truckers because they: Reduce signal blind spots caused by your own trailer and other obstacles on the road. Increase your range in front and behind your truck at the cost of a shorter range on either side.

Can you run 2 CB antennas together?

Requirements for Dual CB Installs When installing a dual CB setup, you need an absolute minimum of 5′ between the two antennas. Anything closer, and the antennas will be too close to perform properly. Ideally, you should be closer to 9′ as a minimum for peak performance.

Why do truckers have 2 CB antennas?

With antennas on both sides of your vehicle, you’re much less likely to have large dead spots because the antenna system can “see” more. This is one of the primary reasons most 18 wheelers have dual antenna setups. Without them, the large trailer being pulled would create large dead spots.

How do I increase the range of my CB radio?

There are several procedures for ensuring maximum output.

  1. TUNE THE RADIO. A CB radio is only as good as the coax and antenna connected to it.
  2. USE CB-SPECIFIC ANTENNAS.
  3. ESTABLISH A GROUND PLANE.
  4. CHECK THE VSWR.
  5. ELIMINATE RESISTANCE.

How can I boost my CB radio signal?

A Step-by-Step Guide on How to Increase Watts on CB Radio

  1. Step 1: Check the Manual.
  2. Step 2: Pick the Right Location.
  3. Step 3: Add an SWR Meter.
  4. Step 4: Install a Good Antenna.
  5. Step 5: Invest in an Amplifier.
  6. Step 6: Use the Radio’s Manual Squelch.
  7. Step 1: Pick a CB Radio for a Specific Application.
  8. Step 2: Look for an RF Gain.

Are CB linear amplifiers illegal?

Although the commission has eliminated many citizens band rules, such as the requirement that CB operators be licensed, it still strictly enforces the ban on so-called linear amplifiers, which can increase the power of a CB signal from the authorized 4 watts to several hundred watts.

Do truckers still use CB radios 2021?

Citizens Band Radio Service (CBRS) had its hay day in the ’70s, but truckers still use CB radios on a daily basis. In February 2021, Overdrive Magazine conducted a poll about CB radio usage. Their survey found that more than 50% of respondents use their CB radio every day for a variety of purposes.

What is co-phasing and how does it work?

Co-phasing involves placing two (or more!) identical antennas either side-by-side or one over top another (“stacking”) at a certain distance apart (usually a 1/2 Wavelength or more) and feeding the antennas in-phase. The result is 3 db more than just a single antenna.

Why co-phase antennas?

Why co-phase antennas then? Well, co-phasing beams with 3 or more elements results in seriously high-gain. If you are serious about phasing your antennas (any antennas, do not let my ideas and opinions stop you from co-phasing your antennas) then lets get started.

What are some possible physical arrangements for co-phasing?

Lets look at some possible physical arrangements for co-phasing. Figure 5 shows two cubical quads stacked side-by-side. This is the most common arrangement. A stacking boom must be made to support the two antennas. HERE is the plan for a stacking boom designed by Antenna Specialists. I do not know of anybody that commercially makes a stacking boom.
