A 3 element wideband 14MHz OP-DES (Opposing Phase Driven Element System) Yagi

The OP-DES is the newest in patent technology produced by InnovAntennas and is specifically designed for maximum performance, wide-band HF applications. InnovAntennas use the latest in Electromagnetic Design Technology to ensure the very best results and the OP-DES Yagi is proof of that!

This antenna has a flat SWR curve covering 14.000 - 14.350MHz at 1.3:1 SWR.

F/B: 13.5dB @ 14.150MHz

Peak Gain: 7.52dBi

Gain at 20m above Ground: 12.66dBi

Peak F/B: 14.2dB

Power Rating: 5kw

SWR: Below 1.3:1 from 14.000MHz to 14.350MHz

Boom Length: 4.2m

Weight: 12.79Kg / 28.19LB

Turning Radius: 5.790m / 18.86ft

Wind Loading: 0.63 Square Metres / 6.81 Square feet

Wind Survival: 160KPH / 100MPH (125MPH version available upon request)

Other options available if higher wind loading/survival is required.

Stacking Distance: 9 - 12m ( 11m recommended)

2 Stacked Gain @ 11m spacing: 10.49dBi

2 Stacked F/B: 12.18dB

2 Stacked Gain @ 11m Spacing 20m above ground: 15.16dBi


This antenna is made with 1.25 inch (31.75mm) tube tapering to 3/8 inch (9.525mm) at the tips. This antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts as standard, larger upon request.  Boom is 1.5 inch square 16SWG aluminum.


Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, this ensures they work as well as our software model predicts (VHF).

Note: much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make up or our antennas have least effect on performance and pattern degradation.
