RG Mounting Alternatives

There are several options for mounting RG series rain sensors. Depending on the physical constraints, mounting may be on the roof, against a wall, or on an antenna mast either vertically or horizontally.

General Guidelines

Position the RG Sensor so it is not shaded by overhead structures that would inhibit precipitation on the lens or to be shaded during the day as the sun progresses across the sky. This can best be achieved with a South facing location. If on an antenna mast, the preferred orientation is to the south.
Align the housing so the mounting bracket (or base of the unit) is horizontal.
While Cable Ties and Hose Clamps can be used to attach the RG housing mount to a mounting pole, it may be difficult to tighten them adequately. This can cause the unit to rotate and that may affect the performance of the sensor. A preferred method of attachment is to use stainless steel bolts and nuts, drilling through the mounting pole as required.

Aerial Mounts

Vertical Mount

The RG housing can be modified for this solution to make for a more esthetically pleasing assembly.
The side supports can be removed by carefully cutting them at the base of the housing with a hack saw (and yes, we have replacement housings if they are required).
Suggested equipment:
1/2″ EMT compression connector
1/2″ EMT conduit
Remove the wire gland and bore out the center opening to approximately 13/16″ (21mm) to accommodate the compression connector. Remove the nut on the1/2″ EMT compression connector, insert the threaded end into the housing from underneath and secure the connector with the nut. Cut the 1/2″ EMT conduit to the desired length and insert the conduit into the compression fitting. Tighten to secure the connector to the conduit. Dress and route the RG power, ground and signal wires through the conduit and terminate to the RG board. Place the board on the plastic bosses, place the shade on the board. Insert the O-ring into the Lens and fit the assembly to the housing. Secure with the stainless steel screws.

Vertical Mount

RG Vertical mounting

To mount the assembly into an existing antenna mast, the Shelley Aerial Mast Clamp (or equivalent) is a recommended way to go.
Shelley Antenna Mast Clamp

Shelley Antenna Mast Clamp

This clamp allows the smaller diameter assembly to be attached to the larger diameter antenna mast.

Horizontal Mount

Suggested equipment:

Antenna Mount Kit

The Shelley Aerial Mast Clamp is again a good place to start, although there are other ways to get there, including this Antenna Roof Mount Kit.

Antenna Mount Kit

Using 3/4″ x 3′ Aluminum Square Tubing (or equivalent) for the horizontal mast, drill holes into the tubing to mount the RG Housing. Attach screws to lock the housing to the tubing.
Drill holes into the tubing to receive the U bolt from the roof mount antenna kit.
Attach the U bolt to the Antenna Mast, the back clamp to the U Bolt, the tubing to the U bolt and then the washers and nuts to the U bolt. Tighten the nuts to secure the assembly.
Terminate the wires to the RG board as described above. Assemble the RG unit as described above. Insulate and route the wires through the tube and down the mast.

Wall / Roof Mount

A wall or roof mount is a variant of the above mounts.
Suggested equipment:
J tube antenna mount, such as the Winegard DS-3000 or equivalent
Mount the base to the wall or roof with the appropriate hardware. Orient the pole to either a vertical position or horizontal position as needed.
Attach the RG housing using the guidance above.
