View the manufactures page for D220R View the eham review page for D220R Mobile Mini Discone Antenna (100 to 1600MHz for receiving) (144/440/904/1200MHz for transmitting) Specifications: 1/2wave(144MHz), 2x5/8wave(440MHz) Bands: 100-1600 MHz. Antennas: Phased Array manufacturers, service companies and distributors are listed in this trusted and comprehensive vertical portal. Description: The discone antenna has a useful frequency range of at least 10 to 1. 50 ohm coax cable is recommended for transmitting. In Preparation for the ECE Board Exam make sure to expose yourself and familiarize in each and every questions compiled here taken from various sources including but not limited to past Board Examination Questions in Electronic System and. Our 6 Meter Rigid Dipole is a very portable center-fed 1/2 wave antenna that can be used vertically or as a horizontal antenna. DS-150S Scanner & Transmitting Discone Antenna 25-1300 MHz 300MHz VHF/UHF Super Discone. thick disc and cone elements make the antenna highly robust to withstand rough weather. A discone antenna consists of three main parts: the disc, the cone, and the insulator. My main 3 antennas are a Royal Discone , a Watson colinear (white stick) for 2 and 70cm (VHF & UHF) and a Scanking wide range receive verticle antenna (the larger white stick.

In this video from Peter Parker (VK3YE), we get an idea of how simple telescoping, carbon fiber/fiberglass poles can be used to support verticals, slopers, and dipoles in portable or emergency operations. Diamond® Antennas are sold through authorized dealers. The mast is not. Discones have unique features that make good scanner antennas, but are they the right choice for your setup? Would a J-Pole better suit your purposes?. How to increase the range of a radio scanner Radio Scanning has come a long way since the old 'Rock Boxes' of the 1970's. Discone antennas are very useful when very wideband usage is needed. Pretty young female doing ham radio What about using satelites as repeaters for ram radio. The antenna has been in continuous service since. Discone Design Using Simple N-coniiector Feed Theodore S. Conclusion. Due it’s low VSWR as 1:2 over complete UHF operation band from 300-3000 MHz, this discone antenna can be used as a transmitting and receiver. Free Online Engineering Calculator to quickly estimate the geometric Size of the Parts of a Discone Antenna. Product design and specifications are subject to change without notice or obligation. Adding to your cart. This item is currently out of stock. Tarar2, Farooq A. SWR (standing wave ratio) is typically 1. The Discone antenna is remarkable in that it is capable of receiving and transmitting over a wide range of frequencies with good matching. Discone antennas are vertically polarized wideband antennas with omni directional pattern. TRAM 1411 SUPER Wideband Discone Scanner Base Antenna 25-1300 MHz Receive - $59. Cellular / PCS Terminal. View Products >>. About 92% of these are antennas for communications, 3% are tv antenna, and 1% are connectors. We simplify by talking about "polarization of the antenna" instead of "polarization of the signal transmitted or received by the antenna. MODERN ANTENNA DESIGN Second Edition THOMAS A. 11 or Wi-Fi interfaces. His instructions show how to build it out of parts and tools sourced entirely from hardware and electronics. My discone weighs about 10lbs, offers very little wind resistance, and although it is ugly, works well as a VHF-UHF scanner antenna. Height approx. (We tried 160m but it had a very high SWR) The Green Valley ARC goes a great job. Discone antennas Most monitoring enthusiasts have one; it is like having an antenna for every frequency between 25 and 1300 MHz. overcome the limitations of the so called line-of -sight transmission and reception. The Gain is 0 dBd or 2 dBi. There are a few specialty Discone antennas with adjustable whip pieces at the top.
