    Thanks for doing this build video, Joshua. Very helpful to see your technique. What power supply are you using for the Pinecil? Do you have a battery you like to use with it for when you travel? Thanks!

      I am running it from my 100Ah homebuilt power bank that stays topped off with solar. I run a boost converter to 22v and feed the pinecil which will then pull up to 70w. Works very well for me. For portable I run two of my 12v LiPo batteries in series for 24v. If needed the pinecil will do most solder jobs at 12v as well! Joshua N5FY

      Thanks! I just ordered a Pinecil so I appreciate you sharing that info. How do you monitor the voltage on the LiPOs in series? Sorry these aren’t antenna kit questions… I love your design choices on them though!

      I don’t monitor. I use packs that have the same cells and configuration. Then check them against each other when voltage is getting to about 20%. They just don’t drift far from each other.

    Good instructive video. Thanks, might substitute the words diagonal cutters for "strippers".

    What's the gauge of the babana connectors? Maybe 2 millimeters? Take care

    • @N5FY
      @N5FY  10 месяцев назад

      Yes, those are 2mm indeed.

    What soldering iron are you using?

    • @N5FY
      @N5FY  10 месяцев назад

      That is a Pinecil. I really like the small iron!

      @@N5FY Thanks. Do you have a make model? Or is there a better pencil iron you would prefer? Trying to find one on Amazon.

    You should turn off auto focus

      Thanks for the tip! New Camera, still trying to figure it out! Joshua N5FY

    This is no good 9:1 transformer The reactance of this transformer's primary is only 17.4 Ω at 7 MHz. You need to use a ferrite here, even though you call this T80-2 iron powder a ferrite..A FT82-61 would do the job.
