Technically yes, a CB radio antenna will work with a VHF radio. … For a VHF radio, it is better to use a VHF antenna. There are multiple reasons as to why a CB antenna will not work for a VHF radio properly.
Can a CB antenna be used for UHF radio?
That means the antenna used with a CB needs to be designed to work on CB frequencies (26-27MHz). A VHF/UHF antenna isn’t going to be resonate on those frequencies and will perform extremely poorly.
Do you need an antenna for a VHF radio?
VHF antennas are a crucial part of your VHF installation. Understanding how they work and how to select the correct antenna can greatly improve your ability to communicate with other boaters and shore stations.
Will a CB antenna work with a ham radio?
A CB antenna is for just one band, and that band is for the 11 meter band, and is only sort of near 2 of the Ham bands, and, without modification, will not work on either of them, and most CB antennas are rather lossy as built anyway, so you will not be happy.
How do I choose a VHF antenna?
Marine VHF Antenna Height and Strength
Larger vessels can opt for 12- to 18-foot, 7 to 8 dB antennas. “As a general rule, antenna height should be less than half the length of the boat,” Catoe says. Higher-dB antennas generate greater effective radiated power, and that can translate into greater range.
How high should my VHF antenna be?
In an ideal situation, a VHF antenna will be mounted as high as possible. … On a typical 20ft boat, with an 18ft mast, you can expect to add around 5 miles to your transmission by mounting the antenna at the top of the mast compared to mounting it on the cabin top.
Is a CB antenna the same as a GMRS antenna?
GMRS is repeater capable to increase range, though typically only around metropolitan areas. Antenna: For CB the optimum mobile antenna is 108″ (1/4 wave), anything shorter is a compromise. For GMRS a 1/4 wave antenna is 6″ and needs far less ground plane than a CB antenna so it can be mounted virtually anywhere.
Do I need an antenna for a CB radio?
CB Radio – Most new CB radios come with a microphone, mounting bracket and power cord, so you won’t need to buy those separately. CB Antenna – Without an antenna, your radio is useless! … Failing to tune your antenna can result in poor system performance and even permanent radio damage.
What is 3dB antenna?
A 2dB or 3dB gain antenna is the compromise in suburban and general settings. A 5dB gain antenna radiates more energy toward the horizon (compared to the 0, 2, and 3dB antennas) to reach radio communication sites that are further apart and less obstructed. Therefore, they are best used in flatlands and open areas.
Does AIS require a special antenna?
You often hear the question:”Can I use my VHF antenna for my AIS?” In absolute terms, the answer is:”Yes“. Indeed, VHF and AIS operate on the same frequencies and require the same antenna characteristics. In detail, make sure you position the antennas correctly.
Which is better GMRS or CB?
GMRS is UHF High band FM modulation. Better coverage overall in any of the UHF bands. CB is good for mobile to mobile talking ( I mean car to car). There also is a limitation on the amount of WATTS you can legally crank out of it.
