CB Radio Beam Antennas

 Get Your CB Radio Beam Antenna So You Can Reach Those Distant Places.


Sirio Sy27-4 4 Elements Yagi Beam Cb Antenna

  I remember using my PDL II Beam Antenna and I was always impressed with what I could do with it. Then I remember a friend running a Moonraker 4 Beam Antenna on a 50 foot rohn tower. That Antenna performed really well. I have seen other 8 element beam antennas that just look awesome. My problem was always the space problem. I had to work with what I had and I always did a good job. I have read the reviews on these antennas and they seem to perform very well. So below you will find the specifications on the above antenna.
  • Base station antennas Directional, High-gain Horizontal polarization Factory tuned at mid-band High power handling capability Elements equipped whit waterproof jointing sleeve Made of aluminium alloy 6063 T-832
  • Type: SY 27-4: 4 element Yagi antenna Frequency range: SY 27-4: 26.9-27.5 MHz @ SWR <=2, Impedance: 50 Ohms Radiation (H-plane): directional Polarization: linear horizontal Gain: SY 27-4: 11 dBd, 13.15 dBi Bandwidth @ SWR <= 2: SY 27-4: >= 600 KHz SWR @ res. freq.: <= 1.2 Max. power: 1000 Watts (CW) continuous 3000 Watts (CW) short time Feed system / position: Gamma match / center Connector: UHF-female

Turn That Mobile CB Radio Into A CB Radio Base Station

  I was thinking about the different ways to convert that Mobile CB Radio into a CB Radio Base Station. I remember years ago having a metal holder that my mobile cb radio mounted to and you would slide out the radio and then could slide it onto another holder. This way I could use the CB Radio in my car or bring it in the house and use it as a cb radio base station. I think I still have those old mounting holders around.
  So I was thinking of how I could change a Mobile CB Radio into a CB Radio Base Station today. Well I was looking through my Ham Radio Catalogs and I came across a power supply unit made by samlex. They apparently make them for different manufacturers.So I would measure up your CB Radio and compare it to the specifications of the samlex unit. I have a feeling some of the larger mobile cb radios like the Cobras, Galaxy and some other models may fit better then a smaller size cb radio. Who knows with a little ingenuity you may readjust and get your radio to fit.
  I know MFJ has a unit they sell to make your mobile ham radio easily transported for a field day situation. The Base Station Radio Cabinet may or may not come with a power supply. The ones I came across at Amazon seem to. The units I found at Ham Radio Outlet do not come with the power supply. Either way it would make a nice way to use you mobile cb radio or ham radio as a base station.
  Thank You for reading.
