7. INSTALLATION

7.2.3Installation of preamp unit FAX-5 (option)

Small boats may not afford the space to install a long wire antenna. In this case it is recommended to install the preamp unit with 2.6 meter whip antenna. The preamp unit can be installed two ways:

The base of the preamp unit is designed to accept a threaded extension of one-inch diameter. The pitch of the thread should be 14 threads per inch. The mast itself should be no longer than 1.5 meters to prevent flexing in heavy winds.

Attach the preamp unit to a post with stainless steel hose clamps (option).

1.Fix the preamp unit to the mounting location.

2.Screw the whip antenna onto the preamp unit.

3.If the mast is metallic, run a ground wire (local supply) between the mast and the ground terminal on the preamp unit.

4.Waterproof the junction and other exposed metallic parts with silicone sealant.

How to mount the preamp unit FAX-5

Note 1: An antenna wire several meters in length can be connected instead of the whip antenna. In this case, install the wire antenna fixture (supplied with preamp unit) between the antenna wire and the preamp unit as illustrated above.

Note 2: The preamp unit is powered by the facsimile receiver. To power the preamp unit, set J23 on the RCV Board (in the FAX-30) to the "ACTIVE" position. See paragraph 7.4.
