CHAPTER I - GENERAL INFORMATION

General Description

The Hy-Gain Discoverer 7-2 is an optimum spaced, two element beam for the 40 Meter Amateur band.

The Discoverer 7-2 incorporates the principles of linear-loading which results in lower loss and greater radiation efficiency than is possible with loading coils.

The Discoverer 7-2 features stainless steel hardware and clamps on all electrical and most mechanical connections.

WARNING

When installing your system, take extreme care to avoid any accidental contact with power lines or overhead obstructions.

Failure to exercise this care could result in serious or fatal injury.

CHAPTER 2 -PRE-ASSEMBLY

Preparation for Assembly Corrosion Precautions

FOR OUR OVERSEAS CUSTOMERS:

The United States uses American units of measurement. If you use the Metric System, see

"Converting American Measurements to Metric"

Choose a large clear area to assemble your antenna. The area must be at least 23' x 45' (7m x

14m). If you assemble this antenna over a grassy area, precaution should be taken so that hardware is not accidentally lost during assembly. A concrete driveway is an excellent area for assembly.

TOOLS: The following

tools are required

for

'easy assembly of the Discoverer 7-2.

Tape Measure, 12

foot ......

Adjustable Wrench, 8 inch

Nut Driver, 7/16

Hand

NOTE: When unpacking your antenna, check inside of all tubing for parts

(smaller tubing etc.). To conserve space these smaller articles are sometimes put inside larger pieces.

Check all parts against the Parts List to make sure no parts are missing.

The Discoverer 7-2 antenna is designed to be relatively maintenance free for most environments. All hardware is made of passivated stainless steel, typically grade 304. The internal tooth-type lockwashers used in this antenna are grade 410 stainless steel, and are slightly magnetic. The element tubing clamps are grade

304 stainless steel. Most other metallic parts are aluminum. All insulators exposed to sunlight are made from U.V resistant black polyethylene or black Cycolac®.

We have supplied a 3 oz. tube of Penetrox®A-3 from Burndy Corporation for use as an antioxidant within element tubing assemblies. This prevents aluminum oxide from forming on the aluminum surfaces, especially in coastal environments.

Cut the cap off the tube of Penetrox®A-3. Have some rags available to clean off excess from tubing and hands. Be careful not to get this on your clothing.

Before assembling the tubing sections, abrade the mating surfaces with a wire brush or sandpaper. Apply the anti-oxidant to both surfaces, then assemble joint. Wipe off any excess material.

A light amount of clear lacquer or an acrylic spray

may be used to coat the exterior surface of the element assemblies if this antenna is to be installed near a sea coast. Tighten all joints securely before coating !

All tubing supplied with the Discoverer 7-2 telescopes together. Make all measurement to the given dimensions, plus or minus (+/-), no more than 1/8 inch! The assembly of this antenna will be easier if you read this manual completely through at least twice before beginning assembly. Allow at least 6 hours for assembly.

Double and triple check ALL dimensions after assembly.

BALUN

Lightning

For proper lightning protection you must ground your antenna supporting structure. Grounding will ensure noise-free operation and low SWR. A proper ground consists of a 1/2" x 8' copper-clad steel ground rod driven into the ground approximately 12 inches away from the concrete tower base. Connect the tower to the ground rod using #8 copper wire and commercial noncorrosive ground clamps.

Attachment of

Strip your coaxial cable (maximum 7 inches) and install solder lugs (not supplied) and connect to the driven element as shown in Figure 13. An RF choke made from 12 turns of RG-213/u coax in a

14 inch diameter circle is recommended with a split coax feed.

An alternative is to use a Hy-Gain BN-86 or BN-

4000 50 ohm balun for easy connection to your coax cable. "Pigtail" leads of #10 gauge stranded wire 7 inches long should be used from the balun to the tubing clamps.

Use a good quality 50 ohm coaxial transmission line such as Belden 8214 (foam) or Belden 8237,

8267 or 9251 (solid). Take extra care when soldering connectors to foam dielectric coaxial cable. Weather-proof all connectors, which will be exposed to rain of ice, with Coax-Seal© or another similar substance.

Attach the transmission line to the feedpoint and tighten the hardware securely. Tape the coax to the boom and mast to ensure good strain relief.

Boom Support Assembly

Select the 2 inch ID boom support clamps (Item

No. 62) and the boom support straps (Item No.

61) and assemble on the boom 100 inches from the center of the boom-to-mast clamp as shown in Figure 14. Tighten the bolts securely.

Select the 20 foot boom support cable and cut into two equal lengths with a large pair of wire cutters. Attach one end of each cable to the boom support straps using the thimbles (Item No. 59) provided. See Figure 14. Attach the turnbuckles

(Item No. 57) to the opposite ends of the cable as shown.

Measure the length of the assembled support cable and turnbuckle as shown. Install the 3/8" x

2" bolt, lockwasher and nut in each half so that they will be available after the antenna has been hoisted to the top of the tower. Also, tighten the turnbuckles so they will not vibrate loose. Route both cables along the boom and tape near the boom-to-mast bracket so they can be reached after the antenna has been mounted on the tower.

Installation

CHAPTER 4 - INSTALLATION

Attaching the Antenna to the Mast

Make sure all tubing clamps and anchor screws are securely tightened. Also, make sure all betamatch hardware is tightened securely and free of corrosion.

IMPORTANT: The Discoverer 7-2 is a fairly large and heavy antenna and requires some consideration as to how you are going to get it to the top of the tower. Thoroughly read this section before beginning to install your antenna.

Installation on a Crank-Up Tower

Crank the tower down completely or as low as it will go, and block all sections from moving by using a 2" x 4" piece of wood or a solid iron bar for heavier towers. The block should be inserte$ through the lattice structure before the tower is completely down, then the tower can be cranked down until the block takes the weight off the winch.

Use a ladder to reach the top of the tower. Never climb the lattice structure of any Crank-up

Tower! Attach the mast to the tower and rotator.

(The cast aluminum boom-to-mast bracket should be installed on the mast as shown in

Figure 15.) Attach a gin pole to the tower to assist in lifting the Discoverer 7-2.

Assemble the two cast aluminum brackets (Item

No. l) on the mast at the desired height above your tower. Secure the two brackets together using the two (2) 5/16"-18 x 3" bolts, lockwashers, and nuts (Item Nos. 24, 27, & 26).

You may wish to drill a 5/16" hole through the cast brackets' center hole and through the mast and secure using a 5/16"-18 x 4" bolt, lockwasher, and nut (Item Nos. 66, 27, & 26).

This bolt will prevent the antenna from twisting on the mast in high winds. See Figure 1.

When the antenna reaches the mast bracket, the four (4) 5" bolts should be inserted through the holes in the mast bracket and secured using 5/16"

- 18 lockwashers and nuts (Item Nos. 23, 27 and

26). Tighten all bolts securely. You may wish to use a deep-well socket set to tighten these bolts.

The boom support cables may now be untaped from the boom and attached to the mast. Loosen the turnbuckles and slide the entire assembly up the mast until the boom support wires are straight. Tighten the 3/8" - 16 bolts securely.

Take up any slack in each wire with the turnbuckles, until the boom is level. When taut, tie off the turnbuckles. See Figure 14.

Attach the lifting rope to the balance point of the antenna. The lifting rope should be fed through the gin pole or other pulley arrangement attached to the tower. The other end should be at ground level, available to the ground crew for lifting.

Guide ropes may be loosely looped over the boom ends and used by the ground crew to guide the antenna away from the tower and ladder. The guide rope's two loose ends should be held by the ground crew so that the guide rope can be retrieved.

When installing the Discoverer 7-2 on a guyed tower, you may wish to use a different guide system. If you have insulators on your guy wires, you will need to keep the antenna away from the guy wires as well as the tower. You may wish to use two ropes attached to the ground about 15 feet apart. These two ropes can then be used to slide the antenna on as it is also being lifted. The two ropes will need to be far enough from the tower base to allow some sag and still support the antenna away from the guy wires.

This completes your installation. Happy Dx'ing!

Installation of this product near power lines is dangerous. For your safety follow the instructions.
