Read more about the OP-DES Yagi Here. InnovAntennas use the latest in Electromagnetic Design Technology to ensure the very best results and the OP-DES Yagi is proof of that! The OP-DES offers incredible wide-band performance with a flat SWR from 27-28MHz. No matching devices, coils or traps so ALL your power gets to the antenna and radiated !! This antenna has a flat SWR curve covering 28-28.600MHz at 1.2:1 SWR. Performance Gain: 7.47dBi @ 27.500MHz F/B: 13.44dB @ 27.500MHz Peak Gain: 7.50dBi Gain at 10m above Ground: 12.64dBi Peak F/B: 14.23dB Power Rating: 5kw SWR: Below 1.2:1 from 27.000MHz to 28.00MHz (Can be adjusted for 26.5MHz to 27.5MHz)
Stacking Distance: 5.0-6.5m ( 6.0m recommended) 2 Stacked Gain @ 6.0m spacing: 10.51dBi 2 Stacked F/B: 12.20dB 2 Stacked Gain @ 6.0m Spacing 10m above ground: 15.43dBi Boom Length: 2.1m Weight: 4.84Kg / 10.67LB Turning Radius: 3.34m / 10.96ft Wind Loading: 0.22 Square Metres / 2.37 Square feet Wind Survival: 160KPH / 100MPH (125MPH version available upon request) Other options available if higher wind loading/survival is required.
Specification This antenna is made 5/8 inch (15.88mm) center elements and 1/2 inch (12.7mm) outer elements with the OP-DES end sections 3/8 inch (9.525mm). The 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. Boom is 1.5 inch square (38.1mm) 16SWG aluminum. OTHER TAPER SCHEDULES ARE AVAILABLE FOR THIS ANTENNA, CALL OR EMAIL FOR DETAILS Our antennas are constructed with the best quality materials in order 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. 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.
