InnovAntennas Ferrite Bead Baluns
InnovAntennas Ferrite Bead Baluns are fully assembled and ready to install, to achieve the absolute best performance from an InnovAntennas Yagi or other balanced terminal antennas. In contrast to wound baluns, ferrite bead choke baluns have the advantage of covering a wide frequency range for multiple bands. As required for most Yagi antennas from InnovAntennas with 50 ohm direct feed, ring terminals are installed on one end for the studded feedpoint connection. The other end is terminated in either Type-N or SO-239/UHF Female for the appropriate band coverage and impedance. Heat shrink filled with a UV-resistant adhesive provides a waterproof cover over the ferrite beads on the cable and the connector. Why do I need a Balun on my Yagi? Ferrite Bead Baluns offered by InnovAntennas provide very important functions of a balun, which is not well understood. For proper antenna performance, a ferrite bead balun inhibits common-mode current two important ways; A) it prevents RF flow on the outside the coax shield cable when transmitting, and B) it prevents stray RF noise picked up by the coax cable shield from entering the antenna system and affecting the receiver. What happens on the antenna without a RF choke balun? Several problems can occur. When an unbalanced feedline is connected directly to a balanced antenna with no BALUN in place, common-mode currents will run on the outside of the coaxial cable shield. The Yagi feedpoint is forced out of balance causing a skew and diminished beam antenna pattern and gain. A loss of Front-to-Back ratio (F/B) can occur, as well as detuning that affects antenna frequency, potentially causing increased SWR. In addition to the pattern distorting performance drop, radiation from the antenna feedline can cause interference to home and business electronics. The other very important benefit of using a wideband ferrite bead balun is to reduce received noise in certain situations. While the noise produced by many household products is normally at very low levels, sensitive ham radio receivers can be affected, which can prevents weak signals being heard. RF noise picked up on the coax cable shield will enter the antenna system feedpoint when no ferrite bead choke balun is installed at the feedpoint.

InnovAntennas VertiGO HF Vertical Antennas
InnovAntennas VertiGO HF Vertical Antennas cover multiple bands when fed as a non-resonant radiator using a remote antenna tuner mounted at the base. They can also be fed directly as a monoband vertical and are typically and most easily installed as a ground-mounted vertical, depending on the location and the support. To achieve the matching required by modern transceivers and amplifiers, other shortened vertical radiators use traps or coils but, those components contribute to losses; power lost as heat. InnovAntennas VertiGO Antennas radiate on all bands along their entire length. Radials are required for efficient operation of any HF vertical; 16 or more ground radials are better, where their length isn't critical. A remote tuner installed at the base of the antenna provides maximum efficiency and the best performance on the bands indicated. Higher frequencies will tune but higher angle patterns will limit performance. A ferrite bead choke should be used at the remote tuner on the coaxial cable from the station to prevent it from radiating and collecting RF noise. VertiGO Vertical Antennas from InnovAntennas are available in three different height versions, each with rugged aluminum tubing sections, swaged and slit at the top for the element clamps. Brackets and clamps are included for mounting to a user supplied support pipe.

InnovAntennas 144 MHz OWL Ultra Yagi Antennas
InnovAntennas 144 MHz OWL Ultra Yagi Antennas offer the 2 meter weak-signal enthusiast undeniable low-noise performance with amazing SWR bandwidth, particularly good gain and an excellent front-to-back ratio. Five Optimized Wideband Low-impedance (OWL) Ultra Yagi antennas are available, starting with six element up through ten element models. InnovAntennas' OWL Ultra Yagi beams have been extensively numerically simulated and optimized using special software that includes a 3D simulation of the boom, the insulators, the connector and the cable; an elaborate numerical simulation of these antennas that was inconceivable a decade before. InnovAntenna has achieved the best of what is technically possible for a wideband 2 meter Yagi. The boom of the 144 MHz OWL Ultra Yagi is 1 in. (25mm) square aluminum featuring through-the-boom insulated elements. The adjustable center fed folded dipole has the side opposite the 50 ohm feedpoint connected to the boom, which removes static charge to protect the transceiver. This antenna acts like a band-pass and noise filter outside the 2 meter band, due to rapidly rising impedance. However, the most important feature of OWL Ultra Yagi antenna is optimization for reduced side lobe in the elevation plane, achieving dramatically reduced received noise, even in high ambient noise city locations. The InnovAntennas OWL Ultra Yagis are suitable for all "weak signal modes" on the low end of the 2 meter band due to the optimization for high gain with incredibly low noise for EME, Meteor Scatter, Tropo-DX, Sporadic-E, etc. Despite the robust construction (the antennas can withstand wind speeds of up to 100 mph (160 km/h), the Yagis are still relatively light and thus suitable for smaller masts or for stacking several antennas. The OWL Ultra Yagis do not include a balun, as the coaxial cable connects directly to the loop driven element dipole. The antenna can handle 5 kW, but the recommended choke balun handles a maximum power of approx. 1.0 to 1.5 kW is possible. Exceptionally good SWR is achieved over a wide frequency range. With excellent gain to noise ratios (G/T ratio), the economical InnovAntennas OWL Ultra Yagis are well suited for use in stacked arrays, for EME, satellite or terrestrial operations. Each model listing describes the key benefits of the OWL Ultra Yagi Antennas. Your antenna is a part of your receiver and arguably the most important part of your station. You have spent thousands on radio equipment; make sure you don't short-change your set-up by choosing anything other than an InnovAntennas OWL Ultra Yagi.
