SteppIR’s clever variable length antenna and optional 80 meter coil have moving parts resulting in complexity BigIR needs 4 (or 8 with 80 meter coil) control wires to operate antenna from shack For what you get, the antenna cost is a great value, but is, indeed, not cheap. Founded in 2001, SteppIR manufactures adjustable dynamic antennas in Yagi, Vertical and. The dipole runs parallel to the boom and uses the end elements as capacity hats, creating zero interaction with the rest of the antenna. Among all the dipoles, beams and other types of antennas, the lowly vertical has regained some popularity thanks, in part, to the BigIR SteppIR and, more recently, the 43 foot vertical offered by DX Engineering and Zero Five antennas. • SteppIR (SteppIR Window) o Added a Pause button to the form to disable the controller.

SteppIR and DX Radial plate - Ham Radio Picture - At MyHamShack you get a free personal web page for your shack - Your Shack. Installing a steppir 3 element yagi, installing the30-40m dipole kit, homebrew delta loops, sloper antennas, long wires and half wave dipoles. Join LinkedIn Summary. There is also an appendix on Anntenna Matchbox selection and another on Baluns, including how to build your own simple and effective balun for use with an Asymmetrical Matchbox. This is a new configuration a) attempting to generate a lower takeoff angle and more gain. At the attachment I connect a tramline and an extra wire to secure the opposite side of the tower. STEPPIR ant with 30-40m single element kit, above the 3EL - 2m 4 EL. Antenna Repair and Maintenance is a curation of 13 resources about , Repairing a 40m Yagi, Yaesu ATAS 120 Repair, Cushcraft R7 repair and tests, Cushcraft R5 maintenance, EI7BA's Amateur Radio Pages. Here is the link (updated 10/30/2012):. SteppIR UrbanBeam 40- to 6-Meter. Bill Serra N8NRT Chairman, Prizes. 5 – 54 MHz Tuning Rate: 1. A Truly Broadband, Efficient Low Band Dipole - 2 - W7ZZ and N6RY, c. It allowed me to rotate either side of the boom down tightly against the side of the tower to install the elements. EZNEC models of dipoles from the standard formula, fed directly with 50 ohm coax (blue line) or series matched (purple line). puts the amazing size of this antenna in perspective. Any reuse or redistribution of the contents of this website are strictly forbidden without authorization from MFJ Enterprises, Inc. 10m vertical dipole (on a spare steppIR fiber element) - Juste utilisé pour surveiller le 10m de façon permanente (imaginé et construit par Nico en moins de 30mn) Toutes les antennes situées sur la terrrasse du "beach house" (résidence de vancances pour Marocains fortunés - désert à cette saison) face à l'océan, et environ à 35m au. EZeye bolt-- some SteppIR models have an EZeye bolt. The calculated efficiency on 20 meters is over 90% and on forty it is 45%, which while it may sound bad, is a loss of only a HALF of an S-unit at. SteppIR - Why Compromise? The SteppIR antenna was originally conceived to solve the problem of covering the Yagi antennas must be made a specific length to operate. It offers these great features: Up to Six bands (20 – 6) fed by a single coax Directional with good front/back Low SWR No tuning required, just plug and play Performs well at lower heights Capable of 2,000 watts power Small physical foot print (11 Ft turning radius) …. As a vertical dipole that is "only" 35 feet high, it is definitely a compromise on 80, and only somewhat less so on 40. 06011 Balun, 1:1 with SO239 Connection for Vertical or Dipole 5KW Choke balun in waterproof housing, with 2ea SO239 Connectors; Ideal for keeping RF from coming into the shack over the coaxial cable; $ 77. Join LinkedIn Summary. Frank's N4SPP Ham Radio home-built slinky coil dipole antenna See more. 3L SteppIR Oct 2010 The 30/40 meter “trombone” dipole loop assembly of the 3-element SteppIR can be a challenge if you plan on installing the elements onto the boom after the boom has already been installed on the tower using a PVRC mount. No RSS feed added. On 40m and 30 the element becomes folded back on itself and acts as a dipole. A brief overview of SteppIR technology. Page 21 SteppIR Antennas - 4 Element Prepare the Fiberglass Element Support Tubes (standard poles) Note: If you have ordered the optional 40m - 30m Dipole Kit you need to refer to the section on preparing the poles (ESTs) in that specific manual. 7 dB over a dipole at optimum height. I find it’s low angle of radiation and very low SWR’s on all bands works extremely well for my DX operations. Steppir UrbanBeam and AC6LA's Animated Steppir Models has been engineered to really be a very clever 2 element yagi or bent dipole, and the bands it covers and. No one will even know it's a vertical antenna. 2112 116TH AVE NE SUITE 1-5, BELLEVUE WA, 98004 WWW. To give you an idea of the performance, I worked a station on 20m this evening in Indonesia on just 10w QRP, with a report of 5/7. Each element is variable in length by using a motor driven metal band (Copper Beryllium). Box 352 Alto, MI 49302 *The dbi gain figures are fictitious, but since other antenna manufacturers tend to use them to manipulate things in their favor by enhancing their specifications with phony data, we've added them so that you can get accurate comparisons. First licensed in 1951 as WN2HQL and has been a serious DXer since 1954. A second bidirectional mode (BD-0) supports the SteppIR antennas. His graduate research was focused on log-periodic dipole array (LPDA) antennas where he studied under Paul Mayes, a pioneer in broadband antennas. A shortened 40 meter rotary dipole; W1JR type chokes; Active receive loop; LZ1AQ actieve antenne versterker; F6AOJ RX splitter; cropped-cropped-Header-SteppIr. 37 db on40m over a full size dipole. The SteppIR is a shortened dipole (end loaded). Product (empty). where he performed EMC consulting, managed new EMC product development including LISNs and filters and innovated test methods for specialized electromagnetic testing including high power lightning generators and simulators. It performs to SteppIR specs, and I congratulate them for a superbly engineered product. Anybody have any info on this ? I also noticed that another thread on. Photo: SteppIR. Jim Nies SteppIR – 20m-6m Dipole w/ SDA100 Controller Tom Venson WA4ESI Staunton. 2112 116TH AVE NE SUITE 1-5, BELLEVUE WA, 98004 WWW. The DB42 MonstIR Pro is currently the largest of the Dream Beam series of Yagi antennas, with 5 elements on 20m-6m and 3 elements on 40/30. Installing a steppir 3 element yagi, installing the30-40m dipole kit, homebrew delta loops, sloper antennas, long wires and half wave dipoles. A Tower Project at WØIVJ (Click on pictures to enlarge) Email: [email protected] Well, I finally got around to fitting the new SteppIR 30/40M Kit to my original 2 element SteppIR. At 112 feet is a 40 meter rotating dipole for multipliers — maybe a 2 element 40 meter some day. SteppIR Communication Systems is a world-leader in HF and VHF communications systems. Since FluidMotion rates its SteppIR antennas to 200 watts during tuning, the SteppIR Tuning Relay may prevent an expensive and time-consuming mistake. Also commercial multiband or shortened dipoles work well. 7 or later In a effort to improve the operation of the Steppir antenna and to address the problems that can come up in the myriad of installations we have a new version of firmware for all of our Yagis.
