    Very nice. 👍 Great minds think alike just made a speaker wire antenna this afternoon for some fun. Even easier as you split off enough for a 20m "di-poh" (I thought that was Welsh teletubby 😂) and then the remainder is a transmission line which is connected to a BNC to Banana plug adapter to connect to the radio. Can be even easier for a beginner as you don't even need to do any soldering. The coax version you've done here was the first antenna I made, every new ham should have a go at this one.

    For some odd reason this reminded me of a time when I needed to make a quick and dirty dipole. All I had was a lot of coax that had a PL95 connector on one end. I don't remember what frequency I was running it on at the time, so for brevity we'll just assume I also needed 5m lengths. What I did was measure back from the unterminated coax end about 5m. I removed the outer jacket for that 5m. At the point where the stripped part met the un-stripped part I spread the braid apart just enough to snake the center conductor out. I basically made a dipole by using the center conductor as one arm and the braid as the other arm.

    Amazing how quick and easy it is to build the humble dipole antenna, and how well it works! A dipole really is a great return on the time/energy/cost invested in building and tuning one. 73, KO4AZY

    Hi. Very confused old man here, sorry. Help me right pls. 20mtr wavelenght....1/4 wave = say 5mtr. Is that not tip to tip. Then 2.5mtr per side. See you have 5 per side. Is that not 1/2 wave now? 😊

      Exactly! Dipoles are half wave antennas.

      @M0RMY 4 роки тому +1

      Yep. No need to apologise. It’s a 1/2 wave dipole. Each side leg is a quarter wave. Total length is a 1/2 wave. Have a look here www.everythingrf.com/rf-calculators/dipole-antenna-length-calculator

    Thanks Mike! to tune SWR you have to cut equal lengths at both ends, right?

    • @stewartrv
      @stewartrv 4 роки тому +1

      Yes you need to keep it balanced so cut off the same amount from each end a little at a time. Try and find a clear area to put it up at first, or the place where you'll keep it, as the angle and height above ground will have some effect on it - if you want it perfect. It'll be a little different depending on if it's an inverted V or proper horizontal too.

    Great video Mike .... If you cut wire on a regular basis as i do, I found it much easier to get a 1m piece of dressed 2 x 1 lumber and mark the wood every 100mm down its length and use this as my measuring stick.. Comes in handy to walk down the yard too to get a idea of the length of coax or feeder required. 2m0aki.
