Sourcing Antenna Brackets
The antennas are mounted in the stalls using brackets that are designed and built to suit both the
antenna size and the location where it will be mounted.
Custom made brackets are available for the most common parlor types. These are manufactured
and sold directly from relevant companies.
Note: Custom-made brackets Antenna are available in the US market for the most common
parlor types and are sold directly from relevant companies. Contact your local Afimilk
representative for details.
Note: All brackets are the dealer's responsibility to source (including manufacture and
purchase), according to our guidelines. For further details, contact Afimilk support.

Ordering Transformers (Requirements)
The AfiPass II system requires an isolating transformer that supplies power only to the AfiPass II
Controllers. The size of this transformer depends on the number of controllers it powers.
Caution: The transformer must be supplied with suitable circuit breakers.
The AfiPass II Controller uses up to 36VA during transmission (ID request) and 19VA during idle
operation.
Controllers on the same side of the parlor will never transmit simultaneously, while Controllers on
opposite sides might. Therefore, we recommend installing transformers on each side of the parlor to
power the Controllers on that side.
To calculate the power requirements for each transformer, use the following formula:
𝐏𝐏
=
𝟑𝟑𝟑𝟑
+
𝟏𝟏𝟏𝟏
(
𝐍𝐍 − 𝟏𝟏
)
; where:
•
P = the transformer's required power rating in VA (Volt Amper)
•
N = The number of controllers used.
For example: To power three devices a transformer with a power rating of
𝐏𝐏
=
𝟑𝟑𝟑𝟑
+
𝟏𝟏𝟏𝟏 ∗ 𝟐𝟐
=
𝟕𝟕𝟕𝟕
𝐕𝐕𝐕𝐕
should be used.
