Because the Cobra antenna is a balanced load, it is recommended to install a 4:1 current-style balun at the station end of the feedline (many external tuners provide a built-in balun). Ladder-line feed may have to be trimmed for lowest SWR, but using about a 100 foot length seems to make …
3. For maximum reception, stretch the antenna wire out perpendicular to the station you want to listen to. That means if you draw a make-believe line toward the station, you want to lay the antenna wire out 90 degrees to that imaginary line. You can mount the wire at any height, but consider eight feet for safety. 4.
20-04-2013· The antenna can be mounted pretty much anywhere, but you do need to make sure it's facing the right direction to pick up any stations. The model that John used (the GH0n ) should be able to pick up digital HDTV channels that you're within range of, and works better with UHF or ultra high frequency channels (channels 14-51) than VHF or very high frequency (channels 2-13).

29-11-2007· Step 1, Gather your materials and tools. In order to make the antenna, you will need a large paper clip (50-75 mm, or 2-3 inches long), an empty Bic ballpoint pen, and a roll of electrical tape. You will also need a metric ruler, scissors, wire cutters, and a lighter.Step 2, Straighten the paper clip. Unfold the paper clip into straight piece of metal.Step 3, Measure and cut the paper clip. In order to get the best signal, your paper clip …
A magnetic loop antenna may be the answer and they are not as difficult to build as you might think. Like getting on the air for the first time or taking your license exam there is a certain amount of uncertainty when you first approach magnetic loop antennas, there are a few new ideas to grasp.
02-09-2013· The ZS6BKW antenna is a better match for our bands than the G5RV. The method of construction and tuning is essentially the same for both antennas but the dimensions are different. The ZS6BKW is a "random length dipole" with ladder line …
04-05-2011· It should be 22 inches (55.88 cm) long. Going from left to right with the board laying horizontally, mark lines at the 2 inch (5.08 cm) mark, the 7.25 inch (18.42 cm) mark, the 12.5 inch (31.75 cm) mark, and the 17.75 inch (45.09 cm) mark. Use a marker or a pencil. Mark 2 dots on each line that are evenly spaced.
09-02-2009· I made one little blanket for my cats (-sized one) and did it a lot tighter. I like them both ways, but you use a lot more yarn the tighter you make it. Anyway, I am SO sorry, I don't know how I managed to forget the footage of me finishing the very end of the piece.

Ham radio is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, etc. Developing a ham radio project may requires using an antenna analyser, a device that is used for ...
DESPITE what you may have read elsewhere, short antennas such as the one pictured here do indeed work relarively well on 160m, provide you provision for the high voltage and high current involved. This is possible to achieve on a case by case basis, but not as a generically reproducable solution. If you want to do this, you'll have to do your homework and build it yourself.
09-04-2015· 2. Place the antenna in or near a window. The fewer obstructions between your antenna and the broadcast towers, the better. And make no mistake–thick walls and ceilings are certainly obstructions. That's why placing your antenna in or near a window often yields the best results.
For making our FM dipole antenna, we used some cheap speaker wire. FM dipole made from twin flex. To make up the VHF FM dipole antenna, first the cable should have the two insulated wires split back away from one another and opened out. The centre should then be …
It is easy to build, construct and erect a dipole antenna for the HF bands: 160, 80, 40, 20, 15, 10 metres, etc using a few simple components at a minimal cost and get great results.
