3 Simple Wire Antennas
Welcome to Practical Antenna's longest video yet! In this video, I will show you three simple wire antennas for use in the field. All of them are extremely portable and relatively inexpensive to set up. These are great for field day, backpacking, and everyday use. Enjoy!

Vertically Polarized Delta Loop

In this video, I explain and show you how to build a Vertically Polarized Delta Loop. I set up a model in my backyard, and then traveled to a place that works very well with this type of antenna. As always, you can find more information on this antenna, and others on my website, practicalantennas.com.

      Someone else remembers paper tapes! Actually learned that for winding surveyor’s chains working summers in college. Started at a computer job, still using paper and mylar TTY tapes to boot some of the old machines. My mentor was carefully showing how to do it. I grabbed another tape and had it done before he finished his demo. But it serves the same purpose: rolling up the material without twisting it. The twists are easier to see with flat tape, but will cause kinking and tangles. In fact, I have a separate video just on winding wire and rope using that method.

    You could build a Hentenna if your have another section of tent pole.

    • @practicalantennas1754
      @practicalantennas1754 2 місяці тому

      Yes, or a 50 ohm rectangular loop: practicalantennas.com/designs/loops/loop-sizes/ The Hentenna may have a slight advantage if high enough in the air, but things are more complicated over ground, where increased spacing between the wires (which improves gain in free space) is counteracted by the lower wire being closer to the ground, thereby contributing less to low angle radiation. For a further discussion see practicalantennas.com/theory/loop/full-wave/. Up to around 1 wavelength (top height), there isn’t a significant difference among them, with the delta (point down) having a slight advantage due to more radiation from the top wire, and it is easier to build then a Hentenna.

    So both wires are connected to the centre wire in the coax?

    • @practicalantennas1754
      @practicalantennas1754 2 місяці тому

      Depends which antenna… For the dipole, one wire connects to the coax center conductor, and one connects to the shield. A balun is often a good idea, but not always needed when weight is a critical factor. For the ground plane antenna, both dipole wires are connected to the coax SHIELD to form the radials, and the added wire is connected to the center conductor to make the vertical part. For the loop, one end of the wire connects to the coax center and the other end to the shield. You can also make the loop by starting with the dipole and connecting the far ends of the wires together, but you need to add a bit more wire to get it to resonate properly.

    Hi, I'm a new Canadian ham radio operator and I really enjoyed your video! I learned a lot from it. I have a small backyard in Toronto, about 25-30 feet long and 10-12 feet wide. I've built a random wire antenna, around 80 feet long, in an inverted U shape. I've been able to pick up many stations from the southern US, but I'm struggling to reach Europe and Asia due to my limited budget and terrain (my location is at a lower gradient than my neighbors). Could you please suggest some options for me to improve my signal reception? Thank you, 73. ve3cxv

      That’s a lot to cover in this format! And I haven’t gotten a lot of that material written for my web site yet at PracticalAntennas.com. I’d suggest posting your question on the forums at eHam.net, or a similar site that is more conducive to an extended discussion with more participants. Just for starters: What is your background noise level? If the S-meter reads S6 on background, you need to solve your noise problem in order to hear weaker stations. Are you listening on the right bands when they are open? I’d suggest using VOACAP (www.voacap.com/hf/) to see which bands will be open at what times of day to various cities. I’m in Hawaii at the moment, and it shows (for 50 watts CW) the highest probability for a 20m contact is 65% at 0500Z, while 17m, 15m, and 12m have about the same chance at 1700Z. Then, of course, there is the question of what times hams at the other end will be on the air… On the other hand, if you get on the air during a DX contest weekend, you are likely to hear lots DX stations, although they won’t be in the mood for an extended chat. That’s even before we start talking about antenna choices.

      It' similar to one made by DX engineering which I just bought and installed and it's excellent. Since he takes it down when not using it he doesn't need guy ropes, but if you're going to leave up all the time as I do it's useful to put in at least two levels of guy ropes which is very very very easy to do.

I’ve been using it for around 40 years now, and I’m still learning new things: practicalantennas.com/construction/masts/bucket/ The quality of the rope does make a difference (especially in getting the weight back down), and a narrower bucket seems to result in fewer tangles.

    I truly appreciate your taking the time to make this video. I'm going to post a link for use as a training aid for my local Amateur Radio Emergency Service® (ARES®) volunteers. I hope that you won't mind my sharing some additional tips to go along with your mast raising technique. Attaching a halyard prior to raising the mast will make the antenna installation easier and faster. Using a guy ring made from cheap plastic cutting board or any piece of >/=1/4 inch thick plastic will permit the halyard to be at least slightly free of the guy lines. Installing 2 halyards is never a bad idea. All halyards should be made up as loops; called endless reeves by sailors; to prevent the rope from running through the pulley and falling back to the ground thus forcing you to lower the mast to reinstall the halyard through it's pulley. Antenna elements can be used as guy lines. This is especially useful for crossed dipoles with a common feed point. You'll have to devise a center insulator attachment which will withstand the tension. Tom Horne W3TDH

      Hi Tom, Glad you found it useful. I tried to keep the video simple, so I didn't include the halyard or other additions on the mast to avoid confusion. I discuss those on the website, including photos of supports for dual halyards, etc. I've had many hams try this technique at my Field Antenna Workshops, and even those who weren't very tall or strong could set it up to 28' by themselves, although some might stop at 20' (which is often high enough). I made the video to share the technique with others who aren't local - it really is fairly easy to do. - Dale WB6BYU
