“This time, I’m out in the field (way out in the Arizona desert) Field testing the MFJ Octopus antenna. So how does it hold up in 60 MPH winds, harsh desert environments and portability as a quick setup field antenna system. I used this antenna all week with my Icom IC-7300 and my Xeigu X-5105.”
Octopus antenna hub turns your ham-sticks into four fully balanced dipoles in minutes!
Mix and match any four HF/VHF/UHF bands.
Example: screw in 80,40,20 meter hamsticks and a dual band 2M/440 MHz whip (two on each band) on opposite sides. Now you have an automatic bandswitching 5-band dipole! Rotate it for maximum signal and minimum QRM and noise with a small rotator like Hy-gain AR-500, $129.95.
Works at any height, low for local NVIS and high for DX. At a fixed height, (say 20-30 feet) use 80-Meters for NVIS and 20-Meters for low-angle DX.
Mounts on any mast up to 1-inch in diameter. Use a fiberglass pole on a tripod and you are on the air! Check out our MFJ-1919EX a perfect mount for the new Octopus Antenna.
Perfect fro casual portable operation, limited space, HOAs, field day, camping, and ARES during disasters.
Single coas feed, built-in balun.
Interaction between bands is minimized because the ends are spaced apart at a large angle.
You don`t need an antenna tuner if you carefully tune each dipole. An easier way is to just set each dipole approximately on frequency and use an antenna tuner to operate and widen the bandwidth.
Hamsticks break down to four feet for easy storage.
Eight 3/8-24 threaded connectors for hamsticks. Super stong fiberglass filled ABS base insulator. Your Octopus Hub will give you years of trouble-free service!

MFJ-16XXT Hamsticks handle 250 Watts PEP. About 7 feet fully extended, 4 feet collapsed.
MFJ-26XXT Hi-Q HamSticks handle 600 Watts PEP. Much larger diameter loading coil and wire gauge gives you higher-Q. Lower losses let you dramatically talk further and hear better. 101 inches fully extended, 53 inches collapsed.
