Amateur radio frequency allocations
HF Verticals - HF Antennas - Antennas - Amateur Radio
Recently a student in our Technician License Class realized that it may take quite a few antennas to cover all of the available ham bands. This is a very valid question. Radio amateurs have so many bands available to them, it does present a challenge to figure out the antenna situation. The focus of this article is broader than that, with the addition of HF operation. The General Class license provides greatly expanded privileges on HF.
Antennas… How Many Do I Need?
There seems to be a problem serving the request at this time. If you are an amateur radio enthusiast who uses a ham radio, you'll be able to communicate with fellow ham radio operators or even report emergencies. However, to operate such a radio effectively, you first need to understand its various features. One important component of a properly functioning ham radio is the radio antenna.
Dipoles are widely used on bands like 80 metres, 40 metres, 20 metres, 15 metres and 10 metres where they can provide excellent levels of performance. Building am HF ham band dipole does not have to be expensive. Often the items needed can be salvaged from previous antennas, or bought for relatively small cost. Building the antenna and erecting it can provide a great insight into the aerials or antennas and how they work, and in this way the performance of the station can be enhanced even further. The most straightforward way to install a dipole is as a horizontal antenna, although this is by no means the only way.
