This allows for much faster threshold measurements. The antenna resonates in the range of frequencies 1.74 to 2.177 GHz. The main parameters for the optimum design of discone antenna considered were Resonant frequency fr, V.S.W.R, reflection. Antenna is said to be in good performance when the reflection coefficient is below -10 dB. There is a good impedance match from 460 MHz to 2.3 GHz. When you plot the S-parameters over a wide range of frequencies, you can observe wideband characteristics of discone antenna. Radiation Pattern. Plot radiation pattern at 470MHz. After reading a bit, I bought a Winegard HDTV preamplifier for $60...it covers 800 mhz which is the frequency range for my state's new integrated government system. Discones generally don't have much gain associated with their design. ... The discone antenna is at 30FT as oppose to the beam which is at 25FT and I am using 40FT of coax RG-213. The frequency range 20MHz – 1300MHz will have you covered for most situations. You can use it to listen to police scanners, ... 3 – Tram 1411 Broad Band Discone/Scanner Base Antenna. The design of this antenna makes you feel like. Discone Antenna This is a relative of the 1/4 wave ground plane antenna optimized for wide frequency bandwidth. It offers 0dB of gain, on frequencies from about 120-1300MHz, and with a vertical element on top, it is usable down to about 30MHz. ... This is also a single band antenna that offers 2dB of gain in a relatively narrow frequency range. The discone antenna has a useful frequency range of at least 10 to 1. When employed as a transmitting antenna, it is often less efficient than an antenna designed for a more limited frequency range. SWR (standing wave ratio) is typically 1.5:1 or less over several octaves of frequency. The discone antenna is a broadband basic antenna originally designed for VHF-UHF service. Indeed, it is a staple for upper-range scanning receivers. ... about a 2.5:1 frequency range. Even though the antenna is quite basic in concept, its shape seems to elicit strange. A symmetric compact discone antenna for the 3GHz to 20GHz frequency range is presented and characterized. The radiation pattern exhibits excellent frequency independence thanks to a careful theoretical and practical analysis of the radiated spherical modes. The time domain impulse response of the antenna is short and shows very low angular dependence.. The discone antenna has a useful frequency range of at least 10 to 1. When employed as a transmitting antenna, it is often less efficient than an antenna designed for a more limited frequency range. SWR (standing wave ratio) is typically 1.5:1 or. In general the impedance match was poor, with huge oscillations in SWR over the frequency range. The antenna’s ability to receive below 100 MHz is delivered by the (optional) upper vertical radiator, which itself contains a loading coil. ... The discone antenna is on a pipe which is just above the roof line of my house and works very well. Home / Tactical Antennas / UHF discone antenna, dipole, 0.52 m ... Frequency Lower: 200.

So basically A discone antenna is a version of a biconical antenna in which one of the cones is replaced by a disc. It is usually mounted vertically, with the disc at the top and the cone beneath. It is offering a frequency range ratio of up to ~10:1. The radiation pattern in the vertical. Discone antenna (Disco-Con Antenna) FKO-1000. The antenna is designed and assembled the Odessa radio engineer. This antenna has shown excellent results in the field during the day. Operating frequency range of 100-1000 MHz. Main areas of resonance with 1.2 SWR accounted for 2m and 70cm bands. The antenna is equipped with mounting console which allows installation on the appropriate masts with the outer diameter between 25 to 60 mm. REQUEST A QUOTE Specifications. The "Chicken Coop" Discone Antenna. By: John Hardin KI6DGX. The May, 2010 episode of "The SHARC Report" focused on scanners. We briefly discussed the discone antenna because it works over a broad frequency range without traps or loading coils, and because they're not too difficult to build. Introducing the Ultra Wide Band Antenna. A UWB antenna is designed to work on a wide range of frequencies. Typically much more than an octave of bandwidth. Thats a lot when most antennas stuggle to acheive more the 20 or 30% bandwidths. Often these antenna designs are used for UWB comms systems. The discone antenna has a useful frequency range of at least 10 to 1. When employed as a transmitting antenna, it is often less efficient than an antenna designed for a more limited frequency range. SWR (standing wave ratio) is. Discone Antenna This is a relative of the 1/4 wave ground plane antenna optimized for wide frequency bandwidth. ... UHF TV antenna, try a 4-bay bow tie, it has about 6dB of gain, a 15dB front-to-back ratio and resonates across a wide frequency range. The whole antenna just needs to be re-oriented to vertical polarization. On VHF,. Antenna Experts offer a wide range of military discone antenas covering the HF, VHF, UHF and microwave frequency bands (20 - 6000 MHz) for defense/military monitoring, scanning, receiving, signal intelligence, jamming and transmitting application. Discone antenna (Disco-Con Antenna) FKO-1000. The antenna is designed and assembled the Odessa radio engineer. This antenna has shown excellent results in the field during the day. Operating frequency range of 100-1000 MHz. Main areas of resonance with 1.2 SWR accounted for 2m and 70cm bands. 4m dish or greater Mar 30, 2014 - Build A Simple VHF/UHF Scanner Antenna - A Police Scanner Antenna For The Price of Parts! If you listen to mil air, 800mhz stuff, want amateur 220 band, NOAA satellites, or something like. The discone is chosen due to its wider frequency range. Additionally, a dual-band LNA with around 20 dBi in both VHF and UHF be included. ... 24, and 38 dBi, respectively, to support a link margin of 6 dB. A typical discone antenna (e.g. 118-3000 MHz scanner antenna) will have a gain of less than 5 dBi, so you would end up with negative link. Caution.

A discone antenna is an omnidirectional vertically polarized antenna. This antenna has an exceptionally large coverage, offering a frequency range ratio of up to 10:1 between the upper cutoff frequency and the lower cutoff frequency. The discone antenna wideband coverage makes it useful in commercial, military, amateur radio, and radio scanner. Caution. DC-02M03G02-NP Discone Antenna is an ultra-wideband antenna , which covers 25-3000MHz frequency bands and can be able to use with other various utility ... Frequency Range. 100 to 500 MHz. VSWR (50 Ohms). Windom Antenna - Feed with coax cable 7 8 It is usually mounted vertically, with the di Ultra wide-band >discone. The frequency range is 470 MHz to 710 MHz. We set the discone's first resonance at a frequency below 470 MHz because, as shown in Figure 4, the SWR shoots up below the first resonance. Making the antenna too small incurs a big penalty. A rule of thumb is to set the first resonant frequency at 0.7 times the lowest operating frequency. The discone is thus a broadband antenna because it is a constant-angle antenna. For the proportions shown in Figure 9-44, the SWR on the coaxial cable connected to the discone antenna can remain below 1.5 for a 7:1 frequency range. Overall performance is still satisfactory for a 9:1 frequency ratio. ABSTRACT In this article, an improved design of ultrawideband (UWB) inverted double discone (IDD) antenna is presented. Conventionally, IDD antennas are designed using tapered cylindrical wires as antenna elements. The tapering makes these antennas very fragile and the antennas suffer frequent damage during installation, transportation or even, due to. Our upgraded Discone Ultra-Wideband Antenna is suitable for monitoring communications signals between 25 and 1300MHz. ... Frequency range: 25-1300Mhz: Length: 170cm: Weight: 1 Kg: Maximum radial diameter: 84cm: Mast diameter: ... This antenna picks up all of the frequencies I need and is far better than similar cheaper discone antenna,. The Discone Antenna described here was designed to operate over a frequency range of 700 to 2000 MHz. It is a very small antenna, but very effective. It is vertically polarized. and has an omni-directional radiation pattern. The antenna's two principle elements are a flat conducting disc mounted horizontally atop, but insulated from, a. A discone antenna is a version of a biconical antenna in which one of the cones is replaced by a disc. It is usually mounted vertically, with the disc at the top and the cone beneath. Omnidirectional, vertically polarized and with. The RDA30-90 (RA24-0101-01) is a lightweight wideband VHF wire discone antenna, operating in the 30 to 90 MHz frequency range, ideal for static mobile and man-portable communications applications.
