Crossbow CB Base Station Antenna
(210-0967) Features Faxback Doc. # 31329
The Crossbow antenna is a 1/2 wavelength radiator, and is tuned to 50 ohms
by means of an internal matching transformer and capacitor. It is pre-
tuned, and not adjustable. The 1/2 wavelength design provides good
This antenna is capable of handling an absolute maximum of 25 Watts RF
power; however, the legal limit for citizen's band is 4 W carrier in AM
mode and 12 Watt PEP in sideband. We will neither support nor recommend
its use outside these legal limits.
This antenna may be said to have a 3 dB effective gain over an isotropic
radiator (theoretical 1/4 wavelength wire) due to its radiation pattern
having a greater concentration of power in the lower lobes.
There is no need for a ground-plane or radials with the Crossbow and it may
be used at ground level or any height above terrain within local

That would be the Worng antenna
this is an all metal antenna as i have the main element and base and the top hat
** NONE fiber glass **
the id number is 21-902 if that helps any...
The Radio-Shack/Archer catalog number is: 21-902
IT IS ... That was a critical piece of information (especially for Radio Shack Internet searches)
CB Queries and Research are best found at "CB Tricks"
Archer 21-902 Super-Maxim CB Antenna -- Advertisement (circa 1975)
Archer 21-902 Super-Maxim Antenna Manual
That Radio-Shack page says 1/2-wave vertical .... That is all you really need to know.
The manual shows you that the manufacturer SWAGED the aluminum tubes.
Hy-Gain and a handful of antenna mfg. used this production approach (requires specialized equipment)
Steve Yates and Tom Rauch web pages (I gave you links) --
They show you "How they work" -- This Archer antenna uses a Capacity Top Hat
So you can use (move) as DIY build to where you want to operate antenna (10 meters?)

I don't know what the antenna really is, all i know for sure its a 1/2 wave for 10-11 meters
that's why I was asking for help, but that's all the intel I have to go on unfurnchely ... :(

Wheres can I find a instruction/manual for this antenna the ARCHER 1/2 wave Super Maxim vertical antenna ?

Ah Ha I found it tnx.
Almost all of these antenna parts can be found at your local hardware store OR
DX Engineering vertical antenna parts.
The Swagged aluminum tubing requires specialized equipment to produce.
Hy-Gain / MFJ has that equipment, as well as Maco Antennas.
If you need that type of tubing, contact them for custom replacement.
