Description
4 Meter or 66–88 Mhz Band YAGI ( 70 Mhz)–ex Wescom telecoms some used also all clearing 90.00Each as is–ex-commercial PMR use made either by Procom Denmark or Telecommunications Ltd Dublin.
Type SDH80/3 is a robust Yagi of exceptional bandwidth suitable for
mounting on the side of a mast or tower. Electrical connections are fully
sealed. The integral balun minimizes interaction between antennas on the
same mast and prevents distortion of the polar diagram by feeder radiation.
Two or four SDH yagis can be stacked vertically or horizontally and fed in phase to give
additional gain (Refer to Base Station Antennas
Application Notes). Due to the wide bandwidth characteristic of this
antenna, it is possible to use one antenna for both transmitting and receiving
without introducing any loss. The received signal response of type SDH is
flat to more than 15% of the center frequency
The boom length may cause a shipping difficulty–we can reconfigure the antenna on a shorter boopm
which may have to be extended locally of end mounting the antenna– we have various brackets suitable for stand off mounting–centre mounting & end mounting these typeds of antenna,.
