Omnidirectional Antenna

Model VL-2901-D496 is a small Amateur Dual Band, VHF/UHF Antenna (145-148 MHz, 2m and 420-450 MHz, 70cm Amateur Radio Bands), designed for mobile platforms (vehicles) with height restrictions. Measuring only approximately 4" (10 cm) in diameter and 6" (15.3 cm) tall, this antenna is a very efficient Low Profile radiator. When installed properly on the metal chassis of a vehicle, the VL-2901-D496 will perform comparably with a full size 1/4 wave monopole antenna. For optimum operation, install...

New Product - Available early 2022 Q2 Leadtime: 4 Weeks ARO X-Band, Wideband +5 dBil VPOL Omnidirectional Antenna, Description This antenna was developed as a Vertically Polarized (VPOL) companion/option to our SL-9402-386 HPOL model. Like its counterpart, the SL-9401-700 antenna was designed to offer comparable gain, at +5 dBil. Dimensions were kept similar, enabling a very stable and low VSWR across the entire X-band spectrum. In free space, the antenna exhibits a nominal gain of...

Leadtime: 4 Weeks ARO X-Band, Omnidirectional Antenna, Description This antenna was originally designed to be used by RACONs, or RAdar beaCONs: a device normally used to mark the location of a Lighthouse or a Marine Buoy, as an aid to maritime navigation. RACONs operate within the X-band range of 9.32-9.50 GHz. Traditionally, a RACON signal identified itself on a radar screen as a dash line, followed by a Morse Code signature. The SL-9402-386 was developed as the antenna component of a RACON...

Wideband, Low Profile Transit Antenna/UHF Train Antenna (430-470 MHz) A broadband, rugged, mobile radio antenna designed to service the whole 430-470 MHz UHF band, featuring a DC grounded radiating element. It may be used as a UHF Train Antenna on locomotives and Railroad related applications, such as End-of-Train Devices (EOT/ETD) or Head-of-Train Devices (HOT/HTD). It is also ideally suited as a Transit Antenna, for installation on buses, subway/metropolitan rail assets and stations, or as a...

A broadband, rugged, mobile radio antenna featuring a high ESD (ElectroStatic Discharge) isolation. With modest dimensions of 1.5"/4 cm (OD) x 4"/10 cm (height), this antenna radiates with a typical peak omnidirectional gain of +5 dBil, when mounted on a large metal surface of at least 16"/40 cm radius. This antenna will survive a 20 ft drop onto asphalt and continue operating (see Drop Test results) Internally, the radiating element is DC grounded and the feedpoint is DC isolated beyond 1 kV....

The LL-1001-396 is a small, low profile, omnidirectional AM antenna, covering the Medium Frequency spectrum from 600 kHz to 1.6 MHz (AM Band). It may be used as an AM antenna for Mobile homes, and to monitor the MF spectrum in First Responder assets. The internal radiating structure is self-contained: no ground plane is needed or required for normal operation.This antenna is an enhanced loop, thus its feedpoint is DC shunted (short circuit) and electrically grounded (if mounted onto a grounded...
