Insulators for the wire antennas

The most popular and widespread are wired antennas. These are several reasons for this, one of which is theirs ease of installation and also lower cost. We all know that anyone who wants to be successful in the amateur radio bands must have a good antenna, high quality wire and also insulators.

What is an antenna wire insulator anyway? As the name implies, and every amateur radio operator and technic knows all too well, it is a thing whose main purpose is to separate sections of the antenna wire.

We offer several types of antenna insulators, which we have also divided into packages according to their use. You can choose insulators for bi-directional beverage antennas or for single wire ones.

All plastic insulators are made of high quality PP+PE material. This makes there insulators lighter than their ceramic variants. This antenna insulators are ideal for all wired antennas such as dipoles, loops, Windom, G5RV and also single wire and bi-directional (reversible) RX beverage antennas. Other suitable helpers are insulators - egg shape or end side (or corner) with thread. With round insulators you will appreciate the space for placing the antenna wire - we offer two sizes (lengths) that make it easy to build a two-wire antenna with a fixed space between the wires. Another in the range of insulators is the ceramic egg shape, which although heavier, has excellent RF properties due to the ceramic and is ideal for long wire antennas and for high power transmitters.

HOW TO MOUNT AND HOW NOT TO MOUNT

Installing the wire antenna insulators is easy. As you can see in the following pictures, all that matters is that they are properly attached to the material (wooden beam, wooden pole, tree, metal bar, metal edge etc.) and that the size of the material is correctly chosen.

Depending on the type of antenna insulator, you can use a drill with a special attachment or an ordinary screwdriver that you thread through the hole in the plastic part of the insulator. For an M6 threaded insulator, two wrenches or plies will suffice.

Here are examples of correctly and incorrectly installed insulators with a demonstration of threading a wire or rope through.

CONSTRUCTION EXAMPLE OF BI-DIR ANTENNA

Beverage antennas should be installed more than a wavelength from other large metallic structures, such as vertical antennas, towers, power lines, electric fence wires etc. Antenna units can be mounted on trees, wooden pole or fiberglass rods - DO NOT use metal pipes and never mount this unit with the connectors facing up.

The parallel wire line used to construct the antenna must be perfect balanced transmission line conditions. The wires must be parallel to the ground. A line should not be constructed in a vertical fashion, using single support poles with one wire under the other. The closer the wire spacing of the line, the lower the impedance of the line, and the less critical installation-related unbalances become. When the antenna is ladder-line (300 or 450 Ohm) - twist the ladder line multiple times along its length.

DIMENSIONS

The dimensions of antenna insulators are important when making a purchasing decision. Dimensions are given at product page at the description. More detailed information is shown graphically in the following illustration.
