VHF Corner Reflector |
 SV227The
SY227 is
an excellent broadband high gain comer reflector for use in the 138-174 MHz frequency
range. Its folded dipole feed permits operation under severe weather and ice conditions
without significant change in pattern or VSWR. SY228 The SY228 combines the features of the SY227 with a larger reflector for higher gain which may be needed in certain system applications. Dual and quad stacked arrays are available for gains of 12.5 dBd and 15 dBd respectively. Higher power and/or heavy-duty models are available. |
