Fan Dipole Height, Raytheon for example makes one which is essentially a log periodical set of dipoles and intended to cover a large Other Dipole Directivity Solutions Fan Dipole – Shorter legs dominate radiation pattern as frequency increases. The Fan Dipole antenna, see figure (1) and plate (1), is a High Frequency The 160/80/40 meter multiband fan dipole (lower right) mounted on the tower! CONSTRUCTION DETAILS: In the photo above, the 160 meter section is on The total dipole antenna length and the length of each dipole part can be obtained by using this calculator by just using the desired frequency of operation. It allows you to Explore 23 curated links about Fan Dipole, featuring resources like VE6LK Fan Dipole , WA2HIP Fan Dipoles, Fan Dipoles 10/15/20m and 12/17/30m. pdf), Text File (. But while a classic half I have used my dipole hung horizontally or in a sloper configuration from about 8 to about 12 foot high but I'm thinking about running it I ran a pair of 40-30-20-17 fan dipoles for a few seasons, could always find signals somewhere. This antenna was built with the same quality workmanship This is usually called a "fan" dipole and works well when tuned for lowest SWR. Raytheon for example makes one which is essentially a log periodical set of dipoles and intended to cover a large But I’m quite convinced that the most compromise-free choice is the fan, or parallel, dipole, which is simply a set of dipoles cut for different bands, all connected to a common feedpoint (Fig. Not all Latter-day "Fan Dipoles" have not stayed the course with respect to single-band operation. io? This cannot be undone. Notes: The Fan-Dipole Antenna Calculator was developed to predict the characteristics of a fan-dipole antenna with up-to 5-elements, given physical dimensions entered via slider widgets. Over the years, I have used a few fan dipoles. height in meters for the center of a Fan dipole for multiple bands, efficiency like a mono-band dipole, only one feed line. This is nothing more than a The basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted Vee antenna (30 mhz or less) is 468/freq-in-Mhz for feet and Here's a tip: Fan dipoles can be tedious to trim and tune. txt) or read online for free. I'm considering a 3-run fan using twinlead, to give me 6 But dipoles and inverted-V's can make good antennas --especially on the lower frequencies where multi-element antennas are not Fan dipoles are really just separate dipoles all connected in parallel to a single feed point. Figure 1. This antenna will be custom In case you don't know what an "SRI" dipole is, read the article above in the link. The antenna Five best homebrew fan dipole antenna projects easy to build. Also, the SWR bandwidth on those higher bands is reduced 4-band Fan Dipole Antenna DG. If it is out of tune, adjust the longest wavelength The 3 element fan dipole works very well at covering all the bands 80-6 meters, while using a tuner on the non-resonant bands. 05 wavelengths (7 feet) to 4 wavelengths (560 feet) above good ground. A lower feed For multi-band operation see the sections on Trap Dipoles or Fan Dipoles. It’s reso-nant on 80, 40, 20, and 10 meters, but does require at least 25 feet of hei Fan dipoles are one of the EASIEST ways to get on the air quickly and efficiently on multiple bands. 40m performance won't be amazing at <1/4 wave above the ground or objects, you'll see some weird Dipole Antenna Length Calculator Dipoles antennas are easy to build and can be very effective when placed half a wavelenth or more above ground. In addition to the tricky and tedious tuning procedure, the disadvantages of this antenna also include reduced bandwidth. I was considering a Bob Carver, KB0XT, wants to know how close he can put his dipoles or if he can even combine them? Yes! He can. Traps – Shortens antenna length as Array Solutions Fan Dipoles Manual Thank you and congratulations on your purchase of the Array Solutions, Fan Dipole Antenna System. Updated January 2025 with more 80m data. I'm running one antenna that is a trap dipole on 80/40, and has a 30 meter inverted vee on 30M at the same feed point. Here is a fairly simple and easy to build multi band horizontal fan type dipole that can be constructed for all band operation from 160 meters up thru 6 meters or even higher. The first online Dipole and Inverted V calculator on the page below has been around Latter-day "Fan Dipoles" have not stayed the course with respect to single-band operation. 160/80/40 Fan Dipole 1 - 20 of 22 1 2 Cage, parallel wire, fan or bow-tie dipoles that have a large equivalent diameter or that approximate conical dipoles20 “Bazooka” dipoles with coaxial radiating elements21 Multiple dipoles with Date 1 - 20 of 21 Fan Dipole? The multiband fan dipole is probally one of the most efficient multiband antennas you can build due to the fact that individual dipoles are tuned for each band of operation and fed by one single length of Fan dipoles offer many of the trap-dipole advantages except reduced size.
