Hy-Gain VB-216SAT 16 Element OSCAR Antenna

The Hy-Gain Model 216 SAT is a high-performance “OSCAR” (Orbiting Satellite Carrying Amateur Radio) satellite antenna for the 145.8 – 146.0 MHz frequency band. It features polarization switching circuity for manual selection 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 terrestrial 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.
