What does polarization mean to me?

Vertical polarization is widely used today because it provides an omnidirectional signal path verses a horizontal antenna. Horizontal antennas or a directional vertical antenna can be used in high RF congested areas. But be aware that by using cross polarization (vertical to horizontal) 20 db signal loss will occur.

Antenna gain claims.

Sorry to say but the advertised gain claims of most large antenna companies are exaggerated. There are rules that apply to all antenna systems and like all data it can be manipulated. If you are not sure please contact Skywave Antennas. We are here to help you solve your system antenna problems not just sell…

What is meant by Antenna Gain?

Antenna gain is a measure of directivity of the antennas radiated signal. Remember antennas are a passive device and will never put out more total power than is put in to it. An antenna with gain focuses the power in a particular direction at the cost of reduced power in other directions. This is what…

What does reciprocity mean to me?

The principle of reciprocity applies to most of the performance parameters of an antenna. Gain, radiation pattern, efficiency and many other characteristics have the same value whether an antenna is transmitting or receiving a signal. However, this can’t always be achieved, and each application needs to be evaluated.

A word or two about connectors?

Never use cheap connectors, especially at UHF Frequencies. If the connectors that you use are not using good dielectric properties, the losses could be not only detrimental to your system performance, but would cause expensive down time due to maintenance, and possible intermittent operation. Skywave Antennas manufactures all of their connectors in its own factory…

Antenna configurations?

Although any metallic object will radiate, this doesn’t make it an efficient antenna. There are many antenna configurations: Omnidirectional, Directional arrays, Yagi, Loops, Dipoles, Circular Polarized, Patch, base loaded Whips, Collinear types just to name a few. Each antenna technology has pros, and cons when it comes to their operation. This is where Skywave Antennas can…

Can I mount an antenna inside my enclosure?

An antenna should never be located inside a conductive or metal enclosure. If you mount an antenna outside on your metal enclosure you will need to tune the antenna while mounted because the enclosure becomes part of your antenna system at that point. Also be aware of plastic boxes, although RF signals pass through most…
