How far apart should ham radio antennas be?
With most questions of this nature, there is an easy answer and a not so easy answer. The easy answer is that you should maintain a minimum mounting distance of at least 1/4 wavelength apart for the lowest frequency antenna within the same horizontal plane. For VHF antennas, that translates to roughly 19 inches.
Can you use a TV antenna for ham?
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).
How far should antennas be separated?
Here is the rule: The horizontal distance between antennas should be greater than 1/4 of its wavelength (absolute minimum separation), but it should not be located at the exact multiples of its wavelength (maybe avoid the first 3-4 multiples).
Can an old TV antenna be used for ham radio?
Re: Old TV antenna=Ham Radio Antenna?? You would have to take it apart and redesign it for a VHF or UHF band, that would be about it. A lot of ham antennas are not very expensive to make on your own or “homebrew”. A TV antenna is designed to work quite a bit differently than a ham antenna is.
Can a CB antenna be used for ham radio?
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 big of an area do you need for a VHF antenna?
The easy answer is that you should maintain a minimum mounting distance of at least 1/4 wavelength apart for the lowest frequency antenna within the same horizontal plane. For VHF antennas, that translates to roughly 19 inches.
How big of a separation do you need for a UHF antenna?
It is recommended that a minimum horizontal separation of 2m and 4.5m is achieved for UHF to UHF and UHF to VHF installations respectively. On building roof tops where greater horizontal separation is possible 10m is recommended. 2.2.2 Vertical Antenna Separation
How big of an antenna do I need for two transceivers?
Separating antennas horizontally can take up quite a bit of real estate. Getting the antennas out of their transmit apertures will greatly limit the cross-talk or desense between the two transceivers. Omni-directional antennas like the 2 Meter J-Pole or 2 Meter Slim Jim antennas have a donut shaped radiation pattern.
Can a 2 meter antenna be used as a HF antenna?
Your 2 meter antenna isn’t resonant on HF frequencies and your HF antenna isn’t resonant on the 2 meter band, so their proximity isn’t much of an issue than two VHF antennas next to each other.
