If a wire antenna is slanted above earth, it radiates waves that have both a vertical and a horizontal component. Thus a radiator that is parallel to the earth radiates horizontally, while an antenna at a right angle to the earth (vertical) radiates a vertical wave. 54K likes, 531 comments - International Space Station (iss) on Instagram: An out-of-this-world ham radio contact A few weeks ago, 8-year-old Isabella. Polarization is determined by the position of the radiating element or wire with respect to the earth. Antenna Polarization Most HF-band antennas are either vertically or horizontally polarized, although circular polarization is possible, just as it is at VHF and UHF. Lower frequency antennas, operating between 2 and 10 MHz, should also be kept well away from conductive objects and as high above ground as possible if you want good performance.

This is because the antenna should be clear of conductive objects such as power lines, phone wires, gutters and the like, plus high enough to have a low radiation angle. Any antenna is a good one if it meets your needs! In general, the height of the antenna above ground is the most critical factor at the higher end of the HF spectrum, that is from roughly 14 through 30 MHz. Practically any radiator works well under some propagation conditions, assuming the radiator is able to accept power and radiate it at some useful angle.
If a modest system is the order of the day, then use whatever is practical and accept the performance that follows. You might want to erect the biggest and best collection of antennas that space and finances will allow. Do you want to dedicate yourself to serious contesting and DXing? Are you looking for general-purpose operation that will yield short-and long-haul QSOs during periods of good propagation? Your answers should result in selecting an antenna that will meet your needs. Operation objectives also come into play. Other limitations are imposed by the amount of money available for an antenna system (including supporting hardware), the number of amateur bands to be worked and local zoning ordinances. Those who live in urban areas often must accept a compromise antenna for the HF bands because a city lot won't accommodate full-size wire dipoles, end-fed systems or high supporting structures. The amount of available space should be high on the list of factors to consider when selecting an antenna. Here you'll find simple verticals and dipoles, as well as quad and Yagi projects and other antennas that you can build and use. This chapter, by Chuck Hutchinson, K8CH, covers theory and construction of antennas for most radio amateurs. General Utah Amateur Radio information net.ANTENNA BASICS very ham needs at least one antenna, and most hams have built one.

To give our club members and community an opportunity to get together to talk about different radio topics during this time we are unable to be together in person If you have a Net that you’d like included in this listing, please email us at NameĪRES Training and local Ham Radio announcements. The ARRL has an entire directory completely devoted to listing all Nets.This page will list Nets of interest to Amateur Radio Operators in the Davis County area. It didn’t stay that way for long, however. At that time, number 73 meaning was My Love to You.

There are literally thousands of Nets going on everyday through-out the world. To further shorten the language, some operators might only say eights as a ham radio slang for 88. What is a Net? A Net, in Ham Radio lingo, is an on-the-air meeting.
