Take a tour of the quality found in OptiBeam antennas
Generally
OptiBeam Antenna technologies has put a lot of effort into
numerous carefully designed special assemblies and parts. Extreme mechanical stability and an
outstanding visual appearance are achieved. All screws, nuts, washers, U-bolts etc. are of stainless steel
and each screw used at a dynamic part of the antenna is self securing. The following close up views of the most important antenna
parts show their quality.

 |
Element Mounting
The picture shows the element platform of a driven element (with phase line end connection + phase line stub
concerning modelOB9-5).
The elements are fixed on the platform insulated by means of special UV-resistant tube insulators which come from the machine
industry. The platforms are pre-worked finished parts.
The driven elements are divided with specially
machine worked insulators which are already inserted in the
factory.

|
| Boom to Mast Mounting
To emphasize the mechanical strength of the boom to mast clamps instead
of the usual platforms OptiBeam uses special extremely robust frames. They consist of four right angle aluminum pieces which
horizontally to vertically are mounted in the opposite way.
For the mast mounting 55mm, 65mm or 75mm U-bolts can be chosen.
The boom to mast clamp is a pre assembled finished part.

Coax Connector / Phase Line
Side and rear view of the specially configured
coax socket SO239, mounted on the phase line. The driven elements, arranged in a specific
order on the boom, are connected with a phase line which consists
of two square aluminum tubes. Hereby the drivers are driven in
phase. This system results in a totally loss free and
high efficient feed of the OptiBeam multi-band Yagis. Furthermore real 50 Ohms are achieved at the
feed point for all frequencies of the multi-band Yagi.
The result is an outstanding bandwidth.

|
Element Transitions
Coupling of the element sections 25/20 - 20/16 -
16/12mm. By means of OptiBeams specially designed 'screw-head dive
in technique' and the use of stainless steel screws plus self
securing nuts electrically large surface transitions as well as mechanically
extremely stable connections are achieved.
