INSTRUCTION MANUAL
Model No. VB-216SAT
2-Meter OSCAR Satellite Antenna
Model 216 SAT
GENERAL DESCRIPTION
The Hy-Gain Model 216 SAT is a high-perfor-
mance "OSCAR" (Orbiting Satellite Carrying
Amateur Radio) satellite antenna for the 145.8 -
146.0 MHz frequency band. It features
polarization switching circuity for manual selec-
tion of either Right Hand Circular Polarization
(RHCP) or Left Hand Circular Polarization
(LHCP). This flexible design is suitable for
worldwide applications with any of the amateur
satellites having either an uplink or downlink in
the 145.8 - 146.0 MHz frequency range, such as
AO-10, FO-12, AO-13, DO-17, AO-16, LO-19,
U O-22, KO-23, RS-10, RS-11, RS-12, RS-13,
etc. These include modes A, B, J, JA, JD, JL,
KA, KT, and T.
It is also usable over the entire 2-meter band,
144-148 MHz; and could be used with future
satellites placed near 144.5 MHz, or with ter-
restrial modes such as repeaters and SSB/CW
DX. The vertical and horizontal sets of elements
may he fed with separate feedlines for total
flexibility.
The 216 SAT Antenna features 16 elements
(total) on a 2.1 wavelength boom. Each set of 8
elements is designed to give 10.7 dBd gain based
on a quasi-logarithmic tapering of element
spacings. This design also gives a very clean
pattern, with very small sidelobes. The 216 SAT
also features high efficiency "T" matched driven
elements for easy assembly and high gain. True
R F, 50 ohm switching relays are rated at 200
watts PEP and contribute to improved VSWR.
Feedpoints are encapsulated for long life in all
types of climates. Most hardware is stainless
steel including the element retaining rings
(pushnuts). All insulators are UV protected. The
coaxial assembly is made from high-quality
Polytetrafluoethylene (PTFE) dielectric and
Fluorinated Ethylene Propylene (FEP) jacketed
coaxial cable.
The 216 SAT "OSCAR" beam can be used with
the Hy-Gain 70-30 SAT 70 cm OSCAR Beam
and the 217S, fiberglass, 5 foot boom, or it can
be used with other commercial or "homebrew"
"OSCAR" antennas. The 216 SAT antennas may
be stacked for more gain.
