Are discone antennas any good?
The Skyscan Wideband Desktop Discone Antenna offers impressive coverage across MHz bands of 25 MHz to 2000 MHz, in addition to a durable design. If you are looking for a new VHF-UHF Antenna, the Wideband Desktop Discone aerial could be the one for you.
What is a discone antenna used for?
The discone antenna or discone aerial is often used where an omnidirectional wide band or bandwidth RF antenna design is needed. The discone antenna is used for many radio communication applications from radio scanning and monitoring for the commercial or military services to the home scanner enthusiasts.
What is a Telewave?
Telewave is a provider of highest quality American made radio and wireless system products, including antenna systems, duplexers.
How does a ham antenna work?
Unlike frequencies used by FM radio stations and TV stations, which are line-of-sight and therefore limited to 40 or 50 miles, short-waves bounce off the ionosphere from the transmitter to the receiver’s antenna. The higher the frequency is, the shorter the wavelength.
What is the gain of a discone antenna?
1.75 to 2.3 dBi
The pattern is omnidirectional from 470 MHz to 862 MHz, with the gain ranging from 1.75 to 2.3 dBi. Due to omnidirectional characteristics, discone antenna is used in TV broadcasting systems.
How does omni directional antenna work?
Omnidirectional antennas receive signals equally from all directions. Directional antennas pull in signals better from one direction. In this direction, they can detect a weaker or more distant signal than an equivalent omnidirectional antenna.
Will a CB antenna work for VHF?
Buy only a Vhf antenna. Using a CB antenna will not give you proper performance and will probably damage the transmitter when you broadcast at 25 watts. Since VHF is line of site, the top of the mast is best, buy one designed for this location, as it will be the proper gain.
How long is a ham radio antenna?
Most commercially available antennas come in length equivalent from 1/4 to 5/8’s of a full wavelength. This means that if you want to run a 2m rig (144’ish Mhz),a half wavelength antenna would be 3.3” long, and 3.3 ft is very manageable for vehiclular operations.
