The wood grain looks nice and the Mobile models would fit well in-dash on some of the nice luxury cars with wood grain dash inserts.
Question for you guy`s in the UK?
How many model`s do you guys see for sale, or past models that use wood grain face plates?

]]> CB Band and CB Radios AudioShockwav http://www.worldwidedx.com/cb-band-cb-radios/72715-i-have-often-wondered-why.html EZNEC Models of Your Favorite CB Antennas http://www.worldwidedx.com/cb-antennas/72714-eznec-models-your-favorite-citizens-band-radio-antennas.html Sun, 05 Sep 2010 22:25:15 GMT Well, the XYL didn't have any "Honey-Do's" for me this Labor Day weekend, so I figured I'd take a few moments and model some of our favorite CB Antennas.

Please note that I am using EZNEC DEMO VERSION, which limits me to only 20 segments, therefore all antennas were modeled at 20' above REAL GROUND (at the feedpoints), using #10 awg insulated wire as the elements (exception: Dipole was modeled using #14 insulated wire).

FIRST ANTENNA: 1/4 WAVE OMNIDIRECTIONAL VERTICAL WITH FOUR (4) 1/4 WAVE RADIALS (again, this antenna is at 20' high at the base).

1st attachment shows the antenna and it's currents

2nd attachment shows TOA (Take Off Angle AKA: Elevation Angle) provides a maximum gain of 2.12 dBi (dB gain over a theoretical isotropic radiator) at a 42.0 deg TOA

3rd attachment shows only 1.0 dBi gain at a 12 deg TOA (Elevation Angle, Launch Angle... etc...)

So... how do we make the 1/4 Wave Vertical perform BETTER....

ENTER THE STARDUSTER (AKA: M-400), next installment
