PAC-12 7-50MHz Shortwave Antenna Outdoor Shortwave Antenna 100W w/ Slide Regulator For Ham Radio Details: Note: When using, place metal dome between the two coils. Please not deliberately put on a coil. The following picture shows the new version of the antenna with sliding regulator coil.New metal dome is added to the original one to increase the strength and make the contact between the metal dome and the coil more reliable. The new antenna replaces the adjustment screws and plugs on the original jpc-7 and pac-12 with a sliding adjuster, making it easier to adjust the standing wave. Now, just slide the adjustment slider with your finger. Reference data when using the slider: 14 mega slider is located 6 turns near the side of the rod antenna the gold mark 0; pulls the lever back about 20cm; 7 mega slider is located 4 turns near the aluminum tube side (silver mark), the lever is retracted back about 10cm. Note: Because the matching between the hook adjustment screw and the plastic nut is a little tight, gently clamp the screw with pliers before use, and screw the plastic nut back and forth twice on the screw. The coil bobbin is made by die-cutting. The material is nylon, non-ppr pipe is made by hand. The strength is very high. The coil is now wound with 1.0mm 304 stainless steel wire, which has higher strength and overcomes the deformation of tinned copper wire. The weakness is that all the screws are made of stainless steel screws, and the vibrator aluminum tube is sandblasted and oxidized into black. Note that it is not a simple aluminum rod and two screws.
This is an aluminum tube. Even if it is erected horizontally, the sag is very high.
Small, not as drooping as an aluminum rod is very serious. The base is oxidized to black, and the custom 2.5 m stainless steel rod antenna is used for higher strength and the communication efficiency is greatly improved.
