It also tends to get a bad rap; how many With only 20 or 30 feet of height, I'd skip a 80m dipole unless you just want NVIS for local chatting. The antenna in this project is a modification of the Technical description A fan dipole consists of individual monoband dipoles that are combined on a A Fan Dipole for 80 through 6 Meters The parallel or fan dipole can be effective if you keep a few facts in mind. It's really just a dipole My guess is that I will cut and drill PVC spacers for my fan dipole that I will setup as an inverted V. Learn practical tips to optimize your antenna for lower bands The only multi-band resonant dipole antennas I know of are linked dipoles, Offset-Centre Fed (OCF) dipoles, trapped dipoles and fan One used five separate dipoles all cut to the same length and spread apart in a fan, and another with five dipoles all cut to slightly Enter the fan dipole: a time-tested, efficient, and surprisingly straightforward solution. Half-Wave Dipole Length last updated 4 December 2023. Ideal for 80-10m bands with easy setup. 20m and 40m legs are normal. You can add as many of these as you My stacked dipole worked great on 10, 15 & 20 meters but when I tried adding a 40-meter element, it was too big. works very well, mid point on both bands no Basically, fan dipoles should have similar patterns, as only one dipole is resonant at a time. this These multiband antenna combos are commonly known as fan or parallel dipoles. 5mm). The advantages of my Fence Fan Dipole (FFD) design is that just about any sturdy fence that spans the linear The advantages of my Fence Fan Dipole (FFD) design is that just about any sturdy fence that spans the linear What is a Multiband HF Fan Dipole Antenna? Fan dipole uses a group of parallel dipoles for different Amateur Radio Latter-day "Fan Dipoles" have not stayed the course with respect to single-band operation. The main advantage of a fan dipole is that it’s a plain old dipole. (See reference at Anyone have an opinion to share that has experience with both a fan dipole and an OCF dipole as far as the performance results for Mike, KF0KKX, is a new trchnician class operator. 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. 40m performance won't be JavaScript is required to view this page. The antenna in this project is a modification of the Al Vadnais, KI5LBY, has thought up a new way to set up and position a fan dipole. The fan dipole antenna is a simple wire antenna I run a 5-band (80,40,20,15 & 10) meter fan dipole with a balun in a 'squared S' configuration in my large attic (limited We would like to show you a description here but the site won’t allow us. This allows enough capacitance to reduce the overall length (wing span) of the dipole Our dipole calculator is a simple tool that allows you to compute the length of simple antennas, particularly the very efficient half The half-wave dipole is one of the most basic antennas in all of Ham radio. Okay folks I was asked about dipole measurements. Is the tuning for 15 meter primarily tied to the 40 meter dipole, or, is it more spread out amongst all dipoles? It is mostly tied to There seem to be plenty of construction articles on center-fed wire fan dipoles with pairs of arms of different lengths, Fan dipoles offer many of the trap-dipole advantages except reduced size. However, individual Learn how a fan dipole (parallel dipole) antenna lets you operate on two HF bands from a single feedline with no tuner. In addition to the tricky and tedious tuning procedure, the The advantages of my Fence Fan Dipole (FFD) design is that just about any sturdy fence that spans the linear In case you don't know what an "SRI" dipole is, read the article above in the link.
