Prices 20% less for customers outside of EU A 7 element wideband 24.8-25MHz OP-DES (Opposing Phase Driven Element System) Yagi - NEW FOR 2012 ! Second Generation OP-DES Yagi ! The OP-DES is the newest in patent technology produced by InnovAntennas and is specifically designed for maximum performance, wide-band 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 24.8-25MHz at 1.1:1 SWR. The compact 7el is an antenna with a huge punch over a wide bandwidth, Take a look! Performance Gain: 12.13dBi @ 24.930MHz F/B: 32.27dB @ 24.930MHz Peak Gain: 12.2dBi Gain at 12m above Ground: 16.87dBi Peak F/B: 33.83dB Power Rating: 5kw SWR: Below 1.1:1 from 24.80MHz to 25.0MHz
Stacking Distance: 8.0-12.5m ( 11.5m recommended) 2 Stacked Gain @ 11m spacing: 15.05dBi 2 Stacked F/B: 33.82dB 2 Stacked Gain @ 11.5m Spacing 12m above ground: 19.26dBi Boom Length: 15m Weight: 40.1Kg / 88LB Turning Radius: 7.929m / 26ft Wind Loading: 1.15 Square Metres / 12.35 Square feet Wind Survival: 177KPH / 110MPH - A 125MPH (HD) version is available upon request Other options available if higher wind loading/survival is required.
Specification This antenna is made 3/4 inch (19.05mm) center elements and 5/8 inch (15.88mm) outer elements and 1/2 inch (12.7mm) tips. 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 3 inch (76.5mm) square 10SWG aluminum (3.2mm wall). 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.
