Great video. What does the feed point look like for the octopus antenna. Do we feed individual pairs, or are all 8 centers fed by one side of the coax and the other 8 braids fed by the braid?
I’ve had a terrible time tuning my octopus. It’s now hanging inside my garage not being used. The set screws that you use to move the elements in and out are “soft” metal and the hex portion rounds out way too easily. MFJ promised to send me extra set screws, but that was six months ago- and nothing ever arrived. I’m kind of disappointed . It may be operator error also.
Assuming someone could 3d Print a hub similar to that, but instead of straight out, angle all of the outputs downward slightly, to be more like an umbrella with a series of 4 inverted V dipoles.. and kept relatively close to the ground say 1/10th wavelength or so.. Do you think that it could have potential to operate as a portable(ish) multiband NVIS array?
Hi Dave I'm studying for my tech so no license yet but i have a question , what's the difference between the octopus and a cob web antenna ? And are they both omni directional like a vertical ? And would the be horizontally polarized? Thanks Billy L. From Puerto Rico
Thanks Dave,
Your info about sliding the stinger into the wound coil
Looking good, thanks!

I like your short topics.
Do you need a switch of some sorts to select the dipole pairs on the octopus?
No.
cool, I need to look into them more.

Thanks for explaining that Dave! 15 or 20 feet? How did 40 m and 80 m work on that?

Octopus? Isnt that when your erecting an antenna and have so much wire around you that you get hung up on it? 😋 Thanks Dave!
👍
Nice...............
happy to be the 60th like!
