Are Bingfu antennas any good?
It’s not a great antenna, but you’re most likely looking for a way to conceal it or like my case, keep it from making you vehicle too tall. You won’t reach far stations, but sometimes you can hear them in the noise. The magnet does suck pretty bad…but I have mine mounted in a way that it’s protected from the wind.
Can I use a TV antenna for ham radio?
Yes, but only on frequencies that used to be assigned to tv and are now in use by ham radio operators. Similarly a B-channel 4 antenna may be suitable for use in the 4 meter ham band (70–70,2MHz).
Do I need a balun on my vertical antenna?
No you shouldn’t need a balun. A balun is to match a balanced antenna to an unbalanced feedline. Your vertical is probablu an unbalanced antenna, so no need. A balanced antenna would be something like a centre fed dipole, so you’d use a balun for it.
What is HF antenna?
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).
How far can a 5 watt ham radio transmit?
So according to our rule-of-thumb, 2 people around 6 feet tall using a 5 watt handheld two-way radio, used on flat ground with no obstacles, will have a maximum range of approximately 6 miles.
How high does a ham radio antenna need to be?
9. The number of amateur radio antennas and antenna support structures exceeding the height of 15 feet above ground on any residential lot shall be no greater than is necessary for reasonable accommodation of amateur radio operation.
Does a dipole antenna need a balun?
Paul, a dipole does not *have* to have a balun. Having one may help prevent RF from coming down the line into the shack and may improve the radiation characteristics of the dipole, but I’ve run dipoles connected straight to coax without a problem. Put one up without a balun and see how it works for you.
When should I use an antenna balun?
Baluns are used in many areas to transition between balanced & unbalanced scenarios: one key area is for radio frequency, RF applications for antennas. RF baluns are used with many antennas and their feeders to transform a balanced feed or line to an unbalanced one.
What is a trap dipole antenna?
Trapped Dipole Radio Antennas. A “trap” is a coil and capacitor in parallel having a very high impedance at its resonant frequency. If a trap is inserted at some point along an antenna conductor, that part of the antenna beyond the trap is isolated from the active part and the feedpoint.
What is antenna base?
An antenna is a rod-like part that is comprised of diodes that hoard frequency, allowing you to listen live to your audio or video system. Its antenna base, on the other hand, is the component that secures it in place even under extreme conditions.
What is antenna band?
Antenna was an American indie rock band active from 1991 to 1994. The group was put together in Bloomington, Indiana by John Strohm and Freda Love , who had previously played together in the group Blake Babies .
