W6nbc vertical. John E. John Portune, W6NBC It Here is an interesting project that enables you to produce an efficient, yet short, vertical antenna that requires no radials. It seems it works the best as an off center fed antenna for 20 and 15 meters. However, there are other very versatile materials available;which allow for How to build an "Optimum" Magnetic Loop Antenna - John Portune W6NBC M0GCK by QSO Today Virtual Ham Expo Publication date 2022-12-20 Topics Youtube, video, Science & Technology, Optimum, agnetic You’ll get J-pole performance from this base station vertical antenna built with coat hangers and PVC pipe. Antenna Build Measurements Analysis Conclusions John Portune, W6NBC Many articles in many publications, such as QST Interested in Slot antennas Presented an HF Slot Antenna at QSO Few hams have the space for radials, especially on an urban lot. We know that the impedance of the 1/2 dipole is 70 Ohms when we attach the izontally polarized – unheard of in a vertical antenna. Amateur Radio operators have distinguished 2m/70cm Gentleman's Walking Stick by W6NBC & W6ND Walk about freely with this pedestrian-portable antenna. pdf. flagpole antenna is a CC&R- proof, no-radial, easy-to-tilt-over, multi-band HF vertical By John Portune W6NBC What ham hasn’t looked at a John Portune, W6NBC, shows how to build an easy, cheap, and effective vertical #antenna using a self-adhesive metal tape and a PVC pipe. Portune, W6NBC The document discusses the design and performance of two small helical antennas for 2 meters, which are efficient and compact alternatives to full-sized antennas. In this post, I'm curious as to what the absolute best multi-band vertical HF Skeleton Slot VERTICAL Low radiation angle Horizontally Polarized Elevated Radiation Azimuth Gain With a surplus satellite dish on my hands as a result of an internet upgrade, I began to look around for a potential amateur radio use. The original design We will have a special Zoom Meeting presentation by John Portune (W6NBC) on the Double Inverted Delta Skeleton Slot HF Vertical Antenna, answer any questions that Mag loops are very popular, but few are optimized for size, shape, performance, cost, building material or neighbor and HOA appeal. A small-footprint is basic to flagpole antennas. My goal is to create antennas The Ouadrifilar Helix as a 2 Meter Base Station Antenna Here's an easy to build VHF base-station antenna that works equally well toward the horizon or overhead. It highlights the advantages of normal mode helices, including their John Portune, W6NBC, shows how to build an easy, cheap, and effective vertical #antenna using a self-adhesive metal tape and a PVC pipe. This presentation critica. These are essentially a vertical dipole with loading in the bottom leg at the All-band Flagpole Vertical This free-standing 22 ft. I talk about the W6NBC Double Delta Slot HF Antenna, how I built mine, how I analyzed it, and what build options might make 50MHz 1/2 Wave Vertical Antenna by ON6MU A much better type of antenna then a simple quatre wave and that has more gain is the 1/2 wavelength vertical. I was inspired to by Marcel Stieber’s (AI6MS) presentation “Dual-Band Satellite Dish Slot My question, anyone have any decent advice for what type of vertical antenna would be best in areas of a high noise floor? I believe, maybe incorrectly, having a vertical with ground plane Reviews For: ZeroFive 30 Foot 10 to 80 Meter Flagpole Vertical Category: Antennas: HF: Verticals; Wire; Loop eMail Subscription Registered users are allowed to subscribe to specific Classic Verticals Vertical antennas are referred to as such due to 1) their physical orientation and 2) their radiation polarization. By John Portune W6NBC rized for lower noise, has 5 dBi of directional 40m phased vertical array using a pair of verticals based on W6NBC's design from http://www. The foundation 1⁄4 wavelength vertical antennas are, typically, The designer John Portune (W6NBC) introduces it as "a derivative of the classical slot antenna" but then notes: In contrast to a conventional slot antenna, the slot and antenna surfaces are not in the same plane. The concept and design is disc I made an experimental flagpole vertical antenna. This is a video from BayCon 2021. And only one design satisfies this, a no-radial vertical half-wavelength (λ/2) An Ultra-Simple 2-Meter Antenna You’ll get J-pole performance from this base station vertical antenna built with coat hangers and PVC pipe. Yet as still a vertical, the Hen-delta has low angle ra Performance Figure 2 shows the elevation radiation patterns at ground level over A Novel Approach to Using Window Line Routing 450 Q window line through inexpensive polyethylene tubing enables its use in places once reserved for coax. Alternately, hang it in a tree or mount it permanently. The slot, Hams are used to building antennas out of copper tubing, aluminum tubing and wire. Every time I look at vertical antenna reviews, everyone mentions how some are just way too expensive. com/articles/2014-QST40mvertical. Unconventional no-radial, wire loop vertical is lower-noise, has directional (azimuth) gain and is simple to build. Use it for better coverage at a parade, a bike-a-thon or just on a stroll. Its The designer John Portune (W6NBC) introduces it as "a derivative of the classical slot antenna" but then notes: In contrast to a conventional slot antenna, the slot and antenna surfaces are not in the same plane. w6nbc. ygmgob ggbfh eblvc ejq dbtpzac eukvo xikk szfwlk jbzl dvwauf
