PreciseLOOP® Antenna
V4.0 6-8--2019
Manual Tuned Magnetic Loop Antennas (MLA)
The HG-1 Deluxe, HG-1 Express and SOTA-1 are all manual tuned MLAs. They are designed for quick deployment.
Except for feature differences they all set up the same. The process takes under five minutes. Always check
Assembly
1.
Find a level surface that is clear of any obstructions within
approximately 15-foot radius. Use either the supplied
tripod or use your own. Extend your tripod to a convenient
height. The PreciseLOOP® will work well from two feet or
higher above the ground. After approximately a 6-10 foot
height little is gained in performance.
2.
Assemble the antenna mast. It consists of three sections.
The lower section contains the tuner, the center section
connects the lower and the top section and the top section
contains the induction loop. All it takes is slight pressure to
fit the mast sections securely together. Attach the included
tripod adaptor to the antenna mast.
3.
Attach the tuner to the lower mast section using the
supplied bolts. Mount the mast to the tripod’s standard 25
mm socket.
4.
Spread the radiation loop and fit to the top of the mast.
Make sure the loop element is facing toward the front over
the induction loop. Securely attached PL239 connectors to
the tuner inputs.
5.
Connect the 12-foot, 50-ohm BNC cable, from the induction loop output the transceivers antenna
input. Adjust the loop assembly for a symmetrical appearance.
Tuning
1.
Tuning instructions are also printed on the tuning
enclosure, refer to them as well.
2.
Select the band you wish to use. Set the transceiver to
SSB (this provides the loudest background noise).
3.
Adjust the loop tuner for maximum received noise or
signal (do not use a tuner). Rotate the loop in line with
the desired direction. Maximum gain is approximately
+20dB over the minimum direction. (see illustration at
right).
