Solder the connector to the cable instead of crimping it. Where the air core version is mainly effective at 20 meters, the ferrite core version also provides considerably better damping on the 10 meter band. you want more gain and directivity than can obtained with a dipole? In this When you bring the dipole into a square shape instead of a circle, it has almost the same properties. Kitchen And Bath Dallas| Thank you for visiting my Amateur Radio Blog. Levin Furniture Robinson Town Center| Strip the 5" piece of 18 gauge (or whatever wire you have) and solder a side to each of the driven elements. Even though propagation doesn't favor 10 meter operations now, the band is excellent for local, state, and even regional "rag chews" and informal nets. I initially feed the dipole directly with a 1:1 balun and RG58 coax. on 10 meters, you can build antennas that can have quite a bit of gain and antenna will only work on ten meters. The aluminum tube with which the antenna is attached to the mast is made for this. I read on some sites that I DO NOT need a feed point Transformer.

Build a PVC Ham Radio Antenna Click here PVC Ham Radio Antenna "The picture is an Amateur (Ham) Radio antenna that is about 90 percent PVC pipe and fittings. A disadvantage of multi-core cable is that moisture seeps through the entire cable due to capillary action, resulting in copper corroding. At early of 90's, when I was a CB operator, I begin to build a serious DX antenna. I've posted a 15-meter Moxon video too. You place it at the end of your coaxial cable, as close to the antennas feed point as possible. But building (partly) yourself is actually quite easy, costs half of a new Cobwebb and is also fun to do. Driven Element): It is the feed point where feedline is usually attached from transmitter. and extend its length to about 1.28 of a wavelength overall (0.64 for each But with 7m to 8m wide, theyre still large for a small roof or garden. most of the AM activity occurs on 10 meters, and are shown with antenna In terms of construction you can apply the same shape as that of the Cobwebb, the multiband antenna that follows the same construction principle. As I've stated before, experimentation is what it's all about. Wells Fargo Furniture Credit Card| construction requirement should not be too burdensome. for 0.64 wavelength spacing is shown in Figure 7. A common mode choke does exactly what it says. Fiberglass tubes work great. If you remove the plastic sleeve from the connector, you can easily solder it to the cable. VK2ABQ square, with further refinements to natural beam dimensions by L. B.
