Instructions
Model RMK-II
DO NOT INSTALL THE ANTENNA IN A PLACE WHERE ANY PART OF IT CAN COME INTO
CONTACT WITH POWER LINES IN THE EVENT OF STRUCTURAL FAILURE OF ANY PART OF
THE INSTALLATION OR IN THE COURSE OF NORMAL FLEXING AFTER INSTALLATION,
FOR SUCH CONTACT CAN RESULT IN DAMAGE TO PROPERTY, BODILY INJURY, OR
DEATH!
DURING ASSEMBLY AND INSTALLATION TAKE CARE TO AVOID CONTACTING POWER
LINES WITH THE ANTENNA OR ANY PART OF THE RADIAL OR GROUND SYSTEM. DO NOT
RUN ANY WIRES ABOVE OR BELOW POWER LINES.
TO AVOID A POSSIBLE SHOCK HAZARD CONNECT ALL STATION EQUIPMENT TO A GOOD
EARTH GROUND. FOR GREATER SAFETY, DISCONNECT ALL STATION EQUIPMENT FROM
A.C. POWER BEFORE PROCEEDING.
1. Install the tripod tower at the peak of the roof as
shown. Use three lag screws per base plate to secure
the tower firmly to the roof.
NOTE: The lag screws are best installed if a 1/8" starter
hole is first made for each.
NOTE: Although leaks are not usually a problem, you
may wish to place a 3 1/4" strip of Konnektor-Kote™
(supplied) under each base plate. In addition, you may
wish cover the three base plates with sealant.
2. Loosen the set screws at the top and middle of the
tower and install the MPS Mounting Post Sleeve. The
slotted end with the hose clamp should be up.
3. Tighten the set screws to secure the 1 1/4" tube finger
tight. Do not over tighten, as this will damage the
tube and keep the mounting post from sliding
smoothly.
4. Install the assembled antenna by sliding the (A) mounting post into the MPS as far as it will go and
tighten the hose clamp. NOTE: If the roof is steep or if there is no one to assist you in raising the
antenna, you may wish to install the antenna in the tripod lying on its side and walk or pull the
antenna up, hinging it on two of the tripod's base plates. Alternatively, the mounting post may be
installed and the antenna placed on top of it.
WARNING:
SAFETY FIRST! Although the antenna is not heavy, it may be hard to handle alone or in
windy conditions. A safety belt should always be used when working above ground level.
5. Securely tighten both set screws and lock nuts.
6. Connect the four STR’s to the grounding screw on the (A) mounting post or solder them to the extra
wire coming from the (Q) coil. For antennas from other manufacturers, connect the STR’s to the
same point as the braid of the coaxial feedline.
