    Hey Dave, I made one of your connectors today and just finished the antenna. I have to order some coax and get this thing up on the tower!  Having a ball. Thanks again for your help. 73s

    Glad to hear it. 🙂 You can anchor the ends of the antenna anyway you need to — house, fence rail, dog tie, etc. and one end can be higher than the other. Just try to get the correct angle.  73 and good DX! 🙂

    Hey Dave … I ordered wire to make coils. You are THE MAN! Thanks again for your videos and being a great Elmer. Antenna theory may certainly be beyond the average person but that doesn’t mean that we don’t want to TRY to make a few of our own antennas. Your videos are practical solutions for me. I still have a CB radio in the shack too for emergency communications. I look forward to your antenna ideas for that as well.

    If you have the space try making the 40/80/160m antenna. The tri-band antenna is easier to tune than the 40/80m antenna as it should not require any modifications to the coils. Please visit my website for more information about both antennas. If you have questions then please click the link on my website to my Facebook page. Questions, antenna photos, etc. can be posted on my Facebook page. Thanks for watching and good DX! 🙂

    Hey Dave, Great video.
    Do you have any recommendations for placement of multiple dipole antennas?
    I was thinking of using 2 antennas. One pointed North -South, and the other facing East-West. Will they interact with each other ?

    Many thanks.

    They can still interact with each other if they are too close together. Even though they are running in different directions, they are both still horizontally polarized. Space them as for apart as possible. Thanks for watching and 73! 🙂

    Great job and thanks for including the FD operation at the end… nice antenna. You show that careful tuning can make a big difference in the antenna SWR.

    Well done video. When I got my Novice license in 1970, there was no internet and you were own your own with the help of the ARRL Handbook which was/is excellent. No thought about buying a dipole and I am pretty sure none were available for purchase. You scrounged for any old scrap wire you could find and used the formula to get the desired length. We didn’t have a analyzer so, you had to use your crystal controlled transmitter.Lots of fun. Hi
    Glad you are helping the new guys.

    Thanks for the videos! Very helpful… If we cannot find 1 1/4 caps n plugs…. Can we use 1 1/2 ? Will that affect operation?

    You can use the larger caps and plugs but they will be a bit large. You can also use two caps and a section of PVC pipe. With the 1-1/4″ caps you’ll want to take an SO-239 connector with you while shopping to make sure that it fits as some caps are made with a thicker wall. Also, some guys mount the SO-239 on the outside of a flat cap if doesn’t fit on the inside. Check my website for the feed-point connector parts kit. Thanks for watching and 73! 🙂

    Hello Dave de KE4ELF

    Great video, very informative. You weren’t kidding when you said you had a surprise. When you made contact with W4AM, my old club, I almost fell out of my seat. Anyway, thanks again for the great videos.
