Sirio CB/AM/FM/CELL(900) Fuba Style Antenna

[txrocco@sbcglobal.net (ATS - Patrick Bureau)]

alright going technical, so you are saying that optimum antenna lenght is
16.52 Ft tall, and that only 1/2 (8.26FT) 1/4 (4.13) or 1/8 (2.065FT) are
desirable.

The antenna is 450mm Long (450  Millimeters = 1.476378  Feet) with is a
little less than 1/10 and a little more than 1/12 of the OPTIMAL size.

now I have used THe glue on windshield cb antenna's (1.5ft tall) and have
after SWR gotten 7 miles range oon flat areas with it. So I beleive that yes
this is not the prefered "antenna" for CB radio, but I aint going to be
slapping anytime soon a 72 inch whip behind my rocco, this aint a ford yanno
:)

The specs do advise that max output would be 10Watts, considering I run a
4watt cb radio (unmodified) I think this will do what I need to do (listen
in to truckers for cops) and keep the looks of the rocco fairly close to
intact without adding a CD antenna ontop of my car.

yes its personal choice over "full blown" practicality.

=>A transmitter antenna must be wave lenght matched. Meaning that the full
=>wave frequency for a 27 Mhz radio (cb) is 16.52 feet (both sides + & - of
=>the sinusiodal waveform). Divisors of lenght are allowed but in
=>even steps
=>only. Mismatch the antenna and the forward moving wave (energy) can be
=>reflected back to the transmitter and burn out the output stage.
=>Therefore 1/2, 1/4, 1/8 wave antennas are good. Either that or
=>extra wire is
=>added to balance the load at either the base or in the middle of the
=>antenna, and to fine tune the antenna a matcher (SWR) is added in line.
=>I didn't see this antenna matching the correct frequency for a
=>CB. Maybe the
=>hand held FM jobs on 900 mhz, but not 27Mhz.
