    My Lightning 6 Quad antenna

    As a side note on the L4+. Thanks to Marconi I have a great eznec model of the antenna but would like to put a call out to the 4nec2 experts on the forum to see if it can be converted and the variables setup so we could take advantage of the 4nec2 optimization feature. Does anyone have an...

    Murdog, I have this L6 manual I got from Marconi, hope it helps.

    My Lightning 6 Quad antenna

    JJD, I am very happy with the L4+. I am more of an experimenter than an operator and I wanted to see what kind of distant ground wave or some would say direct wave contacts i could make on 10 meters. Recently I became aware of a net in Omaha on Thursday evenings at 8pm 28.350 and have made...

    Low band noise floor

    Homer, I took the easy way to build a beverage and bought a kit from here. https://remoteqth.com/two-wire-beverage.php I have a 300' ne/sw through the woods that I use mainly for 40m. Makes 40 more pleasant to listen to but it is of course directional. You have to read through the whole page...

    My Lightning 6 Quad antenna

    I have raised the L4+ to about 12' to the boom. SWR and resonance is very similar on vertical and horizontal.

    My Lightning 6 Quad antenna

    I found this so I understand a little bit of what u are talking about. "Folks who have studied this issue suggest that a valid range for the Average Gain is 0.95 through 1.05. Beyond that range, confidence in the results starts to drop." Considering the complexity of...

    Antenna Analyzer vs SWR meter issue

    I use a Rig Expert 600 analyzer and a very accurate Lp-100A SWR/Power meter. The Real RF readings with the meter are nearly always lower than the analyzer readings. Especially if the antenna is not very high off the ground. I have read that this is not so unusual but I really don't know the...

    What do you think overall? The gain is about what I expected, the front to back is not great but that is not to critical for me. What is this spec? AG value of 1.053

    My Lightning 6 Quad antenna

    I was impressed as well when the 3.5" feed point attachment was the sweet spot for the horizontal side. I think LA quoted me the 1.5 SWR BW.

    I'll see how this youtube link to my initial tests goes.

    My Lightning 6 Quad antenna

    Marconi, you are really getting that figured out. This has been kind of a rambling thread but if someone follows from beginning to end I think they will better understand the Lightning Antennas dual polarity quads. And when you have the completed model that will be great! After raising to 10' at...

    My Lightning 6 Quad antenna

    I'm glad you encouraged me to look closer. I ended up with the Horz feed at 3.5" from the end of the rod and the vert feed at the very start of the brass rod. Then I found a way to raise it 3 feet which is 10 feet to the boom and the vertical is starting to look a lot more as you would expect...

    My Lightning 6 Quad antenna

    I forgot to mention the measured SWR is with balun. L4+ 7 ft off ground Horizontal SWR measured LP-100A BW 2:1 ~ 1.4 Mhz 28.075 - 2.01 28.375 - 1.67 28.675 – 1.38 28.975 – 1.25 29.275 – 1.65 29.475 - 2.01 29.575 – 2.26

    My Lightning 6 Quad antenna

    Yes I think I saw a 2db change on one of your plots, I am willing to give up a little RL for a better pattern. I have some data I have collected today. I don't see a lot of change moving the feed point. I moved a couple of inches either side of 3.5" from the end of the rod and 3.5" seemed best...

    My Lightning 6 Quad antenna

    Looks like LA may be off and maybe nobody looked close enough to notice before. I'm headed out to try direct feed no balun just short stub and 1/2wl coax. Attached is the balun specs. I don't really understand RL but it think it looks very good?
