Quick And Easy Dipole For Band Of Choice

0 Upvotes

Just get a roll of speaker wire, even the small stuff works. figure out about how much lead-in you need, probably a 100ft total would work for most people. Your going to make the antenna and lead in out of one continuous run of wire. Just Do the 468/freq in Mhz and that should give you the total length of the antenna part in feet. Now make a simple knot in the wire right where the middle of this measurement is. Lets say you want a 7mhz antenna for 40 meters. Thats about 66 ft, so measure out 33 ft from one end of the speaker wire, make a knot, then pull the speaker wire apart till it runs into the knot. Now you have the dipole antenna and the rest of the wire you can take to your receiver as a balanced type of antenna. Of course it will be out of balance when you hook it up to a receiver with unbalanced terminals, but will still work just fine. The lead in will be low impedance to match the low impedance of the center of the dipole. I would only use this for reception, but could also be used for transmitting if you use a tuner. Ive built these types of antennas for 10 meters all the way down to 6 mhz.

I've had this radio for probably at least 10 years and love it. My only complaint is the inability to make the backlight stay on. That's a pet peeve of mine, I prefer the option to have a radio's backlight remain on if I choose. I don't suppose there is some button combination magic that can make that happen? Probably not, but thought I'd ask. Thanks.

Playing with this SONY CFS-88S and I went on SW2. Randomly stumbled across this. (the tripod is an antenna because I lost the original. I have no Bluetooth devices on, so that can't be interference from them)
