Passive Reflector Dish Assembly

A 27RD Passive Reflector Dish on both ends of a

BH link extends the distance range of the link and

provides a narrower beam width, which can reduce

both received and transmitted interference. A 27RD

on an SM extends the distance range in some bands

(notably 5.7-GHz and 2.4-GHz) and can reduce

both received and transmitted interference in all

bands. The module support tube provides the proper

offset focus angle. See Figure 19.

For 5.x-GHz radios, the reflector gain is 18dB and

the 3 dB beam width is 6° in both azimuth and

elevation. For 2.4-GHz radios, the reflector gain is

11dB and the 3 dB beam width is 17° in both

azimuth and elevation.

LENS

The LENS product retrofits to a radio to

• improve range and resistance to

interference, compared to those of the

module with no reflector.

• provide less wind loading, easier

mounting, and an appearance more

consistent with the module form than has

the reflector dish.

LENS focuses its beam in 60° azimuth and

elevation and boosts signal gain by 9 to 10 dB.

LENS is an option for 5.2-, 5.4-, and 5.7-GHz

radios, but not an option for P7- through P9-

series radios in the U.S.A. or Canada or for 2.4-

GHz radios anywhere.

Viable use cases include all radio types (SM,

BH, and AP), and installation in each case

requires no tools. A dedicated user guide

supports this product.

Currently, the radio types that support LEN

retrofit are PTP 100, and PMP 100 and

PMP 430 SM.
