Product Code – 11M4TORHEAVY

A 4 element Yagi Antenna for the 11m band from our Tornado ‘Heavy Duty’ range. Manufactured from lightweight but extremely strong construction grade 6082-T6 Aluminium stock with a heavy duty boom. The antenna includes Heavy Duty Element Brackets, Heavy Duty Polyamide Element Clamps and comes complete with M10 Stainless Steel Hardware. The antenna has a nice linear bandwidth and will stretch to around 1Mhz 2 to 1 limits although it’s not wide-band – it’s built purely for gain around 27.555Mhz. Also during testing, we found the forward pattern to be quite sharp reducing unwanted QRM from the sides (over 40db) and also to the rear.
Antenna is supplied with all hardware except boom to mast mount (see below). A mounting kit which comprises of stainless steel saddle clamps and U-Bolts, together with an 8mm 6082-T6 Aluminium Plate can also be ordered from the dropdown menus. The mounting kit fits either a 2″ (50.8mm mast/pole) or a 2.5″ (63 .5mm) mast/pole.

All VORTEX Antennas can be shipped WITHOUT any boom to mast mounting plates. Select this option from the drop-down menu when purchasing. Other options include the choice of mounting plates and complete mounting solutions with U-Bolts and Brackets.

We always like to let our buyers see feedback from others:
From a Buyer of this antenna in Germany:

Hi Steve! – The antenna has arrived on Wednesday at me. All is well. Today I started with the antenna. It’s a monster .. HI HI. I’ve had a lot of antennas, but not yet in such a good quality. Unbelievable .. I will probably need several days to understand it all. I’m glad I ordered from you because I do not think I would get anywhere as a good material. Thank you! If I do not understand what I hope for your help.
You and your family a nice weekend!
