Dec 16, 2019 · Here are a couple of antenna videos that I ran across this weekend: The effect of a 1:1 balun on a resonant dipole. While this is an interesting demonstration, what’s not known is how unbalanced the dipole was to start out with. Theoretically, if the two legs of the dipole are perfectly balanced, the balun is unnecessary.. This calculator is designed to give the vertical length (height) of a particular antenna, for the frequency and wavelength chosen. This does NOT take into consideration the type or size of horizontal reflectors, of even if there is a need for them. Enter the desired frequency and select the wavelength.. Taoglas' DCN.01 is a 5G/4G 400 MHz to 6000 MHz wideband omnidirectional antenna Taoglas' Discone One DCN.01 is a wideband, omnidirectional antenna that has been expertly engineered to cover all worldwide 5G and 4G bands, including all Sub-6 GHz deployments across the 400 MHz to 6000 MHz spectrum. The advantages of these antennas are directional, good front-to-back, and smaller than a Yagi. With the tips of the driven element and reflector bent to nearly touch, it squeezes the width of the antenna into a much smaller space. I’ve posted a 15-meter Moxon video too. The Par Electronics Stressed Moxon brings this compact design to six meters. The basic discone structure "consists of a disc and a cone whose apex approaches and becomes common with the outer conductor of the coaxial feeder at its extremity.'4 3 Along with several related antenna forms, the discone evolved from the biconical antenna, or electromagnetic horn. 4. 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.

WF-65 takes smaller mini 4.5/5.0mm F connectors.The inner core is quite fragile and this cable needs to be stripped and terminated with care. This twin coaxial is used for B-Sky B /Sky HD tv installs. Best performance is achieved if you run the feeder coax 90 degrees to the antenna for about 3-4 feet at the feed point. I have one of these on a Grecom PSR-600 scanner. Perfect match. Diamond makes good antennas . As kind of an antenna junkie, myself, the discone is a bit magical. Of course, there’s solid science behind the design, but the frequency range is still kind of amazing with. The main category is Antenna design calculators that is about Antenna design calculators.

GRA-D220R 144/440/900/1200MHz 2M/70cm/33cm/25cm Mini Discone Multiband Wideband Mobile Scanner Antenna, 29 The number 468 divided by the frequency above is the formula for calculating a half wave antenna length used all the time by Amateur radio operators in building many different kinds of antennas First, we should note the. VK1SV calculators page. These calculators are a great way to experiment with antenna designs before you go out and start building. You can try different configurations and get an idea on what the compromises are. Of course, real life is always more complicated, so, for example, a short vertical antenna may have a slightly different capacitance .... Going off of what christ0ph said about the discone, if you aren't necessarily technically inclined, a good starter discone antenna can be picked up at your local Radioshack. Its an oldie but a goodie type of antenna, works well for getting to know the ropes. You can check it out on Radioshack's website. 5. level 2.

Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. A.H. Systems' 7 models of Biconical Antennas operate efficiently over the frequency range of 20 MHz to 18 GHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing. Cut two pieces of wire 53 1/2 inches long (add an extra 1/2 inch or so for connecting the wire to the UHF connector) and one piece of wire 114 inches long. Fashion a 90 degree bend at one end of two shorter pieces at the 12 inch mark. Make a 90 degree bend at 15 1/2 inches on each end of the long piece. Lay the wires on the dry-fit frame and. The result is the bow-tie antenna (also known as a butterfly antenna, or a biconical antenna): Figure 2. The Bow Tie Antenna. This antenna will have a similar radiation pattern to the dipole antenna, and will have vertical polarization. A L =76.5mm Bow Tie antenna with width W =36mm (so that the angle D =2*atan ( 76.5/36 )= 130 degrees). This calculator is designed to give the vertical length (height) of a particular antenna, for the frequency and wavelength chosen.

Discone Antenna Calculator Based on formulas given in the ARRL Handbook Hint : An interesting application note about WLAN discones (2.4 to 5 GHz) by Clemens Verstappen (DL3ETW) appeared in FUNKAMATEUR, 2/2013, p.156 Share your thoughts The webmaster does not read these comments regularely. Urgent questions should be send via email. Most of our calculators are based on already calculated computer models and are based on the principle of scaling size by frequency. Most "linear" wire antennas allow this operation over a wide range of frequencies. In this case, all spatial dimensions change, including the diameter of the wire. Enter the required frequency in MHz, the velocity factor of the coax (if known) and antenna designer will calculate the dimensions of the elements as shown below. Enter Frequency (MHz) Coax velocity factor Velocity Factor = FACT: RF slows down when traveling within coaxial cable.. The discone antenna used in this installation is the Diamond D130NJ. It has an advertised (but exaggerated) bandwidth of 25 to 1,300 MHz. It presently is used mostly in the 118 to 400 MHz aviation bands and is more or less adequate for that purpose. The adjustable antenna will let you find your desired frequency.
