What kind of antenna do I need for ham radio? Wire antenna is the most common type of antenna used in ham radios. People are drawn towards them more than the others since it comes at very affordable price points and is easier to install than others. Besides, its structure is so simple that you can easily make one at home!
How do you make a ham antenna?
Where do I put my ham antenna?
How far can ham radio signals travel?
You can realistically get about 2-18 miles of range with a handheld Ham radio unless you have a particularly powerful base station with a large antenna, in which case your range can be hundreds of miles.
How long is a 2 meter ham radio antenna?
Fully extended, the antenna is 42 inches long but it collapses down for storage (Figure 2). The MFJ-1714 costs less than $20 and comes with a BNC connector. There is also a version that has an SMA connector on it (MFJ-1714S), which is what most current amateur radio handhelds use.

How can I make my own GP antenna?
Why can't I get Channel 11?
It is possible that older antennas, or some newer, cheaper ones marketed as “HD digital antennas” at other stores, may be UHF-only. This has been the most common cause for not being able to receive FOX 11 when all other channels work. There can also be other issues with signal reception.
Do longer antennas work better?
In a nutshell, the longer the antenna the more signals it can catch. So for your truck trying to catch the wavelengths of your radio station, typically what is referred to as a quarter-length antenna is best, so that's about 32 inches long.
Does antenna shape matter?
Obviously, the waves arriving at an antenna from a transmitter are exactly the same, no matter what shape and size the antenna happens to be. A different pattern of dipoles will help to concentrate the signal so it's easier to detect.
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.
How does an RF antenna work?
How a transmitter sends radio waves to a receiver. 1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it.
How do you ground a ham antenna?
Connect one end of the copper wire to the antenna mast with the aid of a mast ground clamp. Then, extend and connect the other end to the house ground. Now that you have successfully grounded your ham radio antenna, you must test the antenna to ensure everything is working absolutely fine.
Can I use the same antenna for CB and ham?
Yes you can put a CB whip and a ham whip on the same vehicle as shown in the photo, and no, they won't "cancel each other out." Remember that hams can operate on many different bands, from 1.8 mHz to something like 2,300 mHz, and the antennas will vary all over the place as to length.
How do you ground a chimney antenna?
Grounding the mast is easy. Simply attach an 8 or 10 AWG copper wire to the mast using a mast ground clamp and run the other end of the copper wire to the house ground. It's recommended to use a separate clamp, and not the one used to ground the coaxial to the house ground.
