the 1.1" antenna extending neatly through the pre-cut notch.
While the first one or two bends can be made using a small hobby vise, the
process will show you why you need some kind of rigid straight edge to
complete the job.
IMPORTANT: While the metal is easy to bend and you are strong and healthy,
your two thumbs are NOT a smooth-metal bending tool. A pair of solid, even
forming edges are required for a straight bend. One edge remains stationary,
and the other edge moves an entire flap evenly into correct position.
Because the shield needs to be soldered securely to the outer side of the PC
board, it is useful to bend each flap slightly more in toward the center, so that
the four sides formed by these flaps can grip the PC board in position for easy
soldering.
MOUNTING THE MICROSTRIP OSCILLATOR:
Performing this operation correctly is absolutely essential to achieving
specified performance and range of the Ramsey SG7 Personal Speed Radar.
Please follow our directions!
 1. Drill a 1/4" hole (no larger) at a distance 1-7/8" from the closed end of the
can. Most coffee cans have indented rings, 1-7/8" is the 2nd ring from the
bottom of the can.
 2. If there is paint on the can, whether it is your’s or the coffee company's,
it must be removed from the 1" X 2" area to which the oscillator assembly
will be soldered.
 3. Use emery paper and/or a stiff wire brush to clean thoroughly the area to
be soldered.
 4. Tin the area to be soldered. An ordinary soldering pencil will work fine for
both tinning and soldering work. It can also be helpful to pre-tin one or two
of the points on the oscillator assembly that will be soldered to the can.
 5. With the oscillator assembly positioned in a straight line (parallel with the
sides of the can), and the antenna centered in the 1/4" hole, solder them
together at two points to hold the oscillator assembly in place.
