ntenna will
be capable of frequencies up to 12 GHz.
This antenna may be teamed with
the Kaul-Tronics ProForm H180 drive system. The antenna is shipped
directly to the user by Kaul-Tronics.

Teamed up with our
1420 MHz UltraCyber Radio telescope or our 1420 MHz
SpectraCyber Hydrogen Line Spectrometer,
will give the user excellent
results.


Note: Kaul-Tronics offers antennas up to 20 feet in diameter. All will work
with our 1420 MHz UltraCyber Radio telescope or our 1420 MHz
SpectraCyber Hydrogen Line Spectrometer

- This tracking system, teamed with the 3 meter antenna
will give versatility to the observer. This unit may be operated with
standard 24 36 Vdc controls, usually found with C band satellite receivers
or customized to operate with your own software controls. This is the same
system used with the SETI League antenna!

The ProForm H180 Tracker may be teamed with the Kaul-Tronics 3 Meter
antenna. The ProForm H180 Tracker is shipped directly to the user by
Kaul-Tronics.

1_" to 2_" (38-63 mm)
Horizontal Boom Diameter:
1_" to 1-5/8" (32-43 mm)
Max. Wind Load:
8.6 Sq. Feet*
Max K-Factor:
578 ft-lb**
Cable Conductors Required:
6 each (Azimuth & Elevation)
* Wind Load specifications assume mounting inside tower on accessory shelf.
** K-Factor: Multiply [Turning Radius] x [Weight of Antenna(s) on Mast]

http://www.yaesu.com/index.html Notes Regarding Rotator Specifications
It is important that the future owner of a rotator knows and understands what the
specifications for a rotator are all about. The information below applies to all
rotators--whether manufactured by Yaesu or not--and is presented in the hope
that it will prove informative to you as you make your rotator buying decision.
What Causes Rotator Failure?
Besides certain avoidable problems (such as upside-down mounting) and Acts of
God (lightning strikes, etc.), the #1 cause of rotator failure is under-specification.
The customer gets a rotator that is too small for his or her application, and its
gears get ground to bits in the first wind storm which occurs.
What Rotator Specification(s) Are Important?
One needs to inspect carefully the turning and braking capability of the rotator,
which needs to be specified in some meaningful way so that the prospective
owner can determine whether or not the rotator is strong enough.
Unfortunately, many rotator manufacturers only specify the strength of a rotator in
terms of how many Square Feet the rotator can hold. This is an entirely
insufficient specification, because it does not account for the distribution of the
mass of the antenna(s) along their boom(s). In other words, ten square feet of
antenna consisting of a lightweight dish antenna (nestle d in close to the mast)
presents significantly less stress to a rotator than does the ten square feet of a 6
meter Yagi distributed along a 60-foot boom. A long-boom Yagi, cubical quad, or
log-periodic antenna can build up considerable momentum during rotation, and
the torque applied to the rotator is not reflected in a simple specification of the
surface area of the antenna. In sum, the total physical size of the antenna(s) must
be correlated to the capabilities of the rotator, and the rotator chosen accordingly.
How Does Yaesu Specify Rotator Turning/Braking Capability?
In addition to the Square Footage of the antenna, Yaesu specifies a K-Factor,
where
K = [Turning Radius] x [Weight of Antenna].
For Christmas Tree stacks, compute the K-Factor (in Foot-Pounds) for each
antenna, then add the K-Factors together. Then compare both the K-Factor and
the Surface Area (in Square Feet) of your antenna(s) to the specifications. If they
both are within the ratings, the rotator will be OK.
