Radio Scanner Magnetic Wideband scanning mini antenna. Description. The WB-225M antenna is a rugged VHF/UHF vehicle antenna with an frequency bandwidth of 200 MHz – 6 GHz MHz. It is well suited for mobile applications … https://en.m.wikipedia.org/wiki/Ultra_high_frequency antenna was a commercially available wideband discone antenna, which is weakly directive along the horizon, and has directivity ¿ 1 toward the sky. The other antenna was a planar spiral, which has a complementary pattern (directivity ¿ 1 toward the horizon, weakly directive toward the sky). The resolution of the survey is.
Welcome to the Scanner antenna page. Here, you'll find links for high gain antennas covering hf-vhf-uhf. In addition, specific models mentioned in the Antennas forum Like diamond antennas,comet, yaesu, icom, watson cushcraft, MFJ and more are here for future reference. radio Antenna sold here,we update our stocks to keep in touch with modern inprovements in Scanner antenna design. A rectangular planar spiral antenna sensor was designed for detecting the partial discharge in gas insulation substations (GIS). It can expediently receive electromagnetic waves leaked from basin-type insulators and can effectively suppress low frequency electromagnetic interference from the surrounding environment. Certain effective techniques such as rectangular spiral structure, bow-tie

the feed, but also the flexibility of the antenna. In this paper, we introduce a side-fed, flexible, ultra-wideband spiral antenna operating from 1 to 5GHz. The concept of side-fed spiral antennas is well known [1,2], and the feed with microstrip tapered infinite balun combines the concept of the infinite balun [3,4] with proper impedance Best Rooftop Wide-Band antennas for base mobile fire and police radio scanner.
