4.1.4 Horizontal Runs
Route waveguide from base of mast to feed-thru flange and from feed-thru
flange to Transceiver.
It can be supported above or below roof. Attach waveguide to horizontal support
member using same type hangers and 4Ft. intervals as in vertical run. Exposed
horizontal runs must be protected from weight of accumulated ice and damage
from falling ice other objects.
4.1.5 Waveguide Connections
Where is possible connect end of waveguide directly to Transceiver and to
Antenna Group input without any short interconnection. (only the adapter must
be used).
Otherwise, assemble rigid waveguide parts in accordance with the typical
installation drawing.
See that gasket and mating surface of flanges are clean. Use comothene,
vythene or other non-flammable fluid for cleaning. Do not apply silicone grease
to flange gaskets. Join flanges making certain gasket is in position. Add
connecting hardware and fasten flanges together, tightening screws evenly.
If factory prepared length of waveguide must changed, cut the waveguide to
appropriate length and attach connector to waveguide after required length of
run has been determined. Attach elliptical waveguide connector to E-bend
elbow through the adapter.
