Vert 2450 Vertical Antenna
(2.4-2.5 and 4.9-5.9 GHz) Dual Band
The AT-415B, engineered with a vertical antenna
rod atop the horizontal dome to provide a "dual" 360[degrees] omni-directional complete coverage pattern, offers consumers excellent non-adjustment reception from various signal origination locations, with a reach of up to 65 miles in diameter.
The 3D antenna gain is combined as a sum of horizontal and vertical antenna
pattern gain and is given as
But the sculpture's vertical antenna
was stolen by vandals and the piece fell into disrepair until the university asked the artist's son Jonathan Clarke, also a sculptor, to restore the sculpture.
Cross Polarization GAIN([G.sub.p]) of vertical antenna
is the same as the "equation (4)" ~.
In addition, the vertical antenna
can be operated in two modes: omni-directional or beamswitchable modes.
In the present work, no correction for receiving vertical antenna
pattern was used; therefore, only measurement farther than 20 m was considered in order to minimize its influence.
The aim of this first field trial was to test a procedure for getting the vertical antenna
phase centre offset.
The system consists of a very high frequency radio receiver, VHF vertical antenna
, workstation, EMWIN software and interconnecting cables.
The radar has one horizontal and one vertical antenna
of large size and deeply modified Yagi-type aerials.
The QFHA is a vertical antenna
, but it can be designed to be low profile, and perhaps retractable, especially for applications in the more compact band-held mobile satellite systems.
MAXRAD has expanded its antenna product line with the introduction of a new low profile vertical antenna
series that provides industry leading wideband performance for virtually any mobile or base station application.
