ERI to Introduce New VHF Television Antenna Gear
At NAB2007, Electronics Research Inc. will unveil three new television antenna products based on the company's new SLIMWing radiator element, which features a low profile mechanical configuration to reduce weight and tower wind load as well as to provide improved azimuth pattern circularity.

The XWING, a top-mounted lattice structure super turnstile television antenna, is available for any VHF television channel from 2 to 13 (47 to 230 MHz). The sidemounted version of the SLIMWing VHF television antenna is intended for applications such as an auxiliary standby VHF television antenna or a main antenna for Class A or LPTV applications. The panel version of the SLIMWing television antenna allows for a wide range of azimuth and elevation patterns that can be custom configured.

The company is also introducing a new UHF television antenna available for rapid deployment for off-air situations or for permanent installation as an auxiliary antenna. The AGW WR1500 Rapid-Deploy Standby antenna is an open-ended waveguide radiator that may be tuned for any channel in the UHF television band.

ERI will also present two new Fine Matcher sections for high-band VHF television. The new matching sections are designed for 3 1/18-inch and 4 1/16-inch systems and are capable of reducing voltage standing wave ratios to less than 1.2:1. Also on tap is a new connector for Andrew HJ11-50B 4-inch air HELIAX.

Finally, ERI will introduce the new ULTRA Guy Anchor, which features a port to allow non-destructive ultra-sonic testing of guy anchor integrity, without soil excavation. In addition to corrosion detection, ERI also offers the MAG-ROD combined cathodic protection and grounding system for corrosion prevention.

Electronics Research Inc. will be in booth N1119.
