Antenna heating system AHS-1022
Depending on size (see Table 2 and Figures А.1–А.3) and quantity of TH, AHU may
have three types:
‒
AHU-1 – small, two THs;
‒
AHU-2 – medium, four THs;
‒
AHU-3 – large, four THs.
From two to four THs ensure heating of each antenna (Figure 3, position 2). AHU
may be delivered with a dome (Figure 3, position 5), and without it. Temperature sensors are
located near THs to monitor current AHU temperature (Figure 3, position 4).
Use data connectors (Figure 3, position 3) and power input connectors (Figure 3,
position 1) to connect KP.
If AHU is applied together with a dome, connect AHU through cable glands at the
bottom of the dome (Figure 3, position 6), and mount it – using mounting studs (Figure 3,
position 7).

Every AHU has an ID number, displayed on the nameplate and set using DIP-switch.
Description of DIP-switch positions and ID number of AHU are shown in Figure 4.
