ALPHA DELTA DX-SWL-S/DX-SWL "SLOPER" ANTENNA

INSTALLATION INSTRUCTIONS

1. Unroll the DX-SWL-S/SWL sloper wire elements, removing any kinks that may have been induced during the packing operation. You will find one wire element 60’ long with two "ISO-RES" inductors, one 16’ stub wire, and one 30’ "Down-Lead".

2. Refer to FIGURE 1: For tower leg or mast mounting, the aluminum mounting bracket will have to be drilled to accept a U-Bolt (user supplied) to fit your particular tower leg or installation method. It should be noted that if your tower is of the "sectional" type (such as Rohn) then the bracket might be fitted to one of the sectional bolts by simply removing the nut and placing the bracket hole over the bolt and reinstalling the nut! In this case, no other hole need be drilled as one hole already exists on the mounting end of the sloper bracket. For other installations simply attach a rope through this bracket hole, with the other end of the rope attached to your mounting point.

3. Installation heights ranging from 20 to 40 feet all seem to work very well. However, the antenna seems to exhibit best overall performance at a mounting height of around 25 feet since this takes advantage of a ground capacitance broadband loading effect.

4. Arrange the sloper so that it will not be in close proximity to any guy wires, metal gutters, sliding or other wire antennas. (Min. of 10 ft. if possible).

5. Attach your coaxial feedline to the Amphenol SO-239 connector on the sloper-mounting bracket. We highly recommend the use of good quality coaxial cable such as RG-58. However any good 50-Ohm cable will suffice! It would be wise to apply some "COAX-SEAL" or other equal weather proofing agent to the feedline coaxial connection and element solder connection.

6. Refer to FIGURE 2: Tying of the lower (tip) end of the sloper should be done so as to allow a gentle slope angle between the antenna and the support structure. We suggest that the end of the sloper be mounted such that it is 8 to 9 feet above ground. This is done as a routine safety measure! Please note that a heavy-duty polycarbonate insulator and special low-stretch nylon rope has been provided for use of the sloper end.

7. The ISO-RES coils have been coated at the factory with two coats of special polyurethane with UV light protectant. They should not be coated with any other material. After having your antenna properly resonant, you might wish to wrap a small piece of "COAX-SEAL" around the bare copper wire ends at the bolt connection on each of the ISO-RES coils. All hardware used is of 18-8 Stainless Steel, and requires no further protection.

8. This completes the installation of your new ALPHA DELTA MULTI-BAND SLOPER ANTENNA.
