Unboxing the New MFJ-2104 MFJ-2104 – Octopus Antenna

QRZ Now - Fri, 12/14/2018 - 07:50

MFJ sent me their MFJ-2104 Octopus Antenna, a four-band dipole with screw-in elements for 75m (the voice portion of 80m), 40m, 20m, and 10m. This is built on a project in Dec 2007 QST by N1GY. The device uses any pairs of hamsticks on any band from 75 to 2m/440cm to create the four bands. It fits on a 1-inch mast. I’ll put it up and test it in a future video.

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.

Tough Octopus Hub
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!
Based on Geoff Haines, N1GY, award-winning December 2007 QST article.

Super Octopus Deals
MFJ-2104, $249.95. Octopus hub with your choice of four (2 each) 250W Hamsticks. Saves $20! When submitting your order choose 4 of the hamsticks listed at the bottom of this page and write them in the notes before submitting your order.

MFJ-16XXT Hamsticks handle 250 Watts PEP. About 7 feet fully extended, 4 feet collapsed.
