This page describes the design and construction materials I used to build a coaxial cable trap. A coaxial cable trap is a parallel resonant circuit that is usually inserted in an antenna element to enable multiband operation. In this case, I wanted to build a 40 meter (7.150 MHz) trap for use in an 80/40 meter vertical <b>antenna</b>.

what information about the report can you expect cps to share with the mandated reporter

But I'm getting ready (saving up) to get a 10 meter ham radio and will be needing a base antenna for it. But my old CB base antenna I had is long gone and I had always wanted to see how a vertical dipole antenna would work. Since 10 meters and cb (sometimes refered as 11meter) are so close in bandwidth often a cb antenna can be tuned for 10 meter.

Repeat for say the upper and lower 2:1 SWR ranges. Trim the antenna a little, and repeat measurements. Once 20m is tuned, repeat with adjusting the coils for 30m and 40m. A fairly cumbersome process, but for three frequency ranges on one antenna, it was a half-hour project at most. In the end, the antenna is less than 2:1 SWR across all of the.

HF verticals are a popular antenna option when trees and towers aren’t available. They are the antennas of choice on the low bands for working DX, as most hams can’t get horizontal antennas high enough to be as effective as a vertical on 80M. They can be surprisingly effective with a good radial or ground system, and disappointing over poor ground.

Three of those were at 5w. the rest were at 20 watts. and all but three were on 20 meters. I compared antennas on a number of signals and the vertical is consistently a couple S units lower on receive.

Drill 1⁄2 inch (1.3 cm) holes using a good drill bit, and never drill close to the end of the pipe. About 2 inches (5.1 cm) from the end gives you a good spacing for the insulators. For the feed point, use yet another piece of PVC pipe, drilling a hole through the center to provide for a strain relief for the feedline.

Today I set up this QRPGuys Tri-Band Vertical as a center loaded vertical, essentially similar to the center loaded Wolf River Coil TIA with long whip and my DIY version of KW4JM's vertical. It has an 11' 1" top section, a 4" coil and 4' 5" bottom section for an overall length or height of 15.

Now its time to add the additional elements to the top and bottom of the collinear array. First add a ¼ wave element to the top of the antenna as shown in Figure 3. Use #16 solid wire or similar and solder it to the center conductor only. The length of the ¼ wave element is calculated as follows: 1/4 wavelength radiator = 300 / F / 4.

A good quality balun (transmission line transformer – BALanced to UNbalanced) is required for the antenna to work properly and to match the impedance, which is higher than that of a resonant dipole. For lower antenna height, usually below 40’, a 4:1 ratio is recommended; for higher antennas, a 6:1 ratio is recommended.
