SCADA MASTERS FOLDED DIPOLE ANTENNAS

 

SM Folded Dipole Antennas are shipped FREE USPS to cut shipping costs
and delivery time. All hardware is provided, you provide the mast or
tower for mounting. For high gain multiple dipole arrays, just folow the 
installation charts for dipole separation. 

YOU CONTROL the radiation pattern by adjusting offset distance from 
mast or tower during installation, (see pictures for patterns)!

For optimized results, the mast should extend ABOVE and BELOW the top 
and bottom dipoles!

BASIC SPECIFICATIONS for all SM-Folded Dipole Antennas:

1/4 wave coaxial line matching circuit provides WIDE BANDWITH with
accurate 50 OHMS matching.

N-FEMALE termination.

All antenna parts are made of high-grade aluminum .

All connections are soldered with 2 layers of sealing. 
 
DC grounded for better lightning and anti-static protection. 

Maximum gain is achieved by coupling single dipoles into a 
phased array. The distance between the center of dipoles is .8
wavelength (See Installation Chart).
