Prices 20% less for customers outside of EU A 4 element wideband 28-28.7MHz OP-DES (Opposing Phase Driven Element System) Yagi
A 6el 10m OP-DES The OP-DES is the newest in patent technology produced by InnovAntennas and is specifically designed for maximum performance, wide-band HF applications. 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! This antenna has a flat SWR curve covering 28-28.700MHz at 1.3:1 SWR. Performance Gain: 9.08dBi @ 28.500MHz F/B: 20.83dB @ 28.500MHz Peak Gain: 9.11dBi Gain at 10m above Ground: 14.16dBi Peak F/B: 20.99dB Power Rating: 5kw SWR: Below 1.3:1 from 28.000MHz to 28.700MHz Stacking Distance: 6.0-7.0m ( 6.5m recommended) 2 Stacked Gain @ 6.5m spacing: 11.90dBi 2 Stacked F/B: 20.93dB 2 Stacked Gain @ 6.5m Spacing 10m above ground: 16.70dBi Boom Length: 3.995m
Weight: 6.15KG / 13.56LB Turning Radius: 3.329m / 10.92ft Wind Loading: 0.2 Square Metres / 2.15 Square feet Wind Survival: 143KPH / 89MPH 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 1.25 inch square 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.
