Overview

InnovAntennas OP-DES Opposing Phase Driven Element System HF Yagis

InnovAntennas OP-DES Opposing Phase Driven Element System HF Yagis are a relatively new development by InnovAntennas. The ends of the driven element of these antennas are angled backwards, parallel to the boom. The opposing phase relationships in them achieves a very clean directional pattern with few side lobes. The resulting performance includes very good gain over a wide frequency range, along with a very good front-to-back ratio. These monoband beams antennas are available in a variety of boom lengths and element counts, to fit in with each operator's needs and their budget.

Feature and Benefits of the InnovAntennas Monoband OP-DES Yagis:

• Have bent driven elements to dramatically reduce side lobes and to help provide with constant performance characteristics
• Super Wide Bandwidth - the broadest SWR, gain and f/b bandwidth of all our antennas, the OP-DES is best suited to HF applications where performance and a wide frequency range of low-SWR are needed in a single package.
• High F/B ratio as with the LFA and OWL, the OP-DES Yagi has an exceptional Front to Back ratio for a direct-feed, 50Ω Yagi, which suppresses unwanted signals from behind your antenna!
• Constant Impedance & 'All-Weather' Stability – Similar to the LFA and OWL, the OP-DES Yagi is able to maintain impedance in wet weather and therefore will not de-tune like other antennas can
• 50-ohm Direct Feed - No Matching Loss - The OP-DES Yagi has been computer optimized with the 'bent' driven element in place to ensure a 50 ohm feed-point with no matching loss and minimal resistive loss
• Class-Leading Direct Feed Yagi Performance - For a given boom length, the OP-DES Yagi provides superior all-round performance as compared to any other HF direct feed Yagi
• Simple SWR Fine-Tuning Feature - No two locations for an antenna are the same. With this in mind the requirements of the perfectionist as well as the everyday user in our sights, the driven element of the OP-DES has adjustable end sections to allow for very simple SWR fine-tuning

The most important part of your receiver - the antenna - has to be the best part. The antenna is considered the most important part of your station. After spending thousands on radio equipment, don't short-change the station by choosing anything less than the InnovAntennas OP-DES HF Yagi.
