(10) Measure the electrical bonding resistance between the conductive fasteners and the conductive surface of the fairing panel.
(a) Make sure the maximum resistance does not exceed 0.5 OHMs.
NOTE: Make the resistance measurement prior to painting
____ the panel and the mounting hardware. If the fairing panels and bolts have been covered with paint, you may not get a correct reading. In this case, use two sharp probes and make sure the probes contact the conductive surface on the panel and the structure then measure the resistance.

NOSE RADOME - DESCRIPTION AND OPERATION
_______________________________________
1. General_______
A. The nose radome extends forward from body station 178. The two main functions of the radome are to serve as a fairing and to house the weather radar antenna and the glide slope antenna director bar.
B. The radome is a cone-shaped structure of fiberglass and is hinged at two places to the top side of the bulkhead at body station 178. Further attachment of the radome is by fasteners which screw into clips on the bulkhead at body station 178. In the open position, the radome is supported by rods.
C. The weather radar antenna is cantilevered from the bulkhead at body station 178.
D. The nose of the radome is equipped with erosion protection. The radome is provided with lightning diverter strips on the exterior surface.
E. The glide slope antenna director bar is a passive element of the glide slope antenna used to alter the glide slope radiation antenna patterns such that the navigation units have maximum glide slope sensitivity. The bar consists of a 13-inch strip of pressure-sensitive aluminum foil tape installed horizontally inside the nose radome approximately 22 inches forward of the aft edge of the nose radome top centerline.
