CO LINEAR ANTENNA DESIGN antenna for average use. It has The choice of a certain design for a particular application is left to the decision of the constructor. This article describes a 5-element collinear antenna design for the 2m band, its This is an introduction to a high gain VHF/UHF vertical collinear antenna program and project that can be an asset to many of you that are looking The quarter-wavelength Coaxial Collinear antenna is an elegant experimenter’s project — blending RF theory and practical Collinear Dipole Antenna Calculator - Calculate Antenna Dimensions This page offers an online antenna designer to calculate the On the basis of a collinear antenna, a rather successful design of the Amos antenna was created. 2 sets of ¼ # **Wire Collinear for 2 Metres By WB3AYW** # A nice 2 metres 5 stage wire collinear, matched j-pole style to be hung from a tree This is a very simple, yet effective 2m antenna made entirely of RG-58 coax. The calculator can be Covers 138-175 MHz 2 Meter vertical with 5. 2 dBi gain derived from the famous extended double zepp antenna design. . 4K subscribers Subscribed Creation date : 23/03/2008 @ 00:43 Last update : 29/11/2025 @ 08:58 Category : 2m Projects Page read 55226 times (Collinear Design) A calculator for deriving the lengths of tubing to be used for the construction of a Super J-Pole Antenna. In selecting a design, certain factors like portability, ruggedness, compactness, signal gain The 2 Meter Collinear J Pole Antenna Project by Sean M3FVB Get ready for field day, mountain topping, emergency communications, roaming or just 2m Collinear 1Kw+ VHF Vertical That Will Last. It describes using CPVC tubing to form coil Band VHF Collinear with 2 Dipoles by SV1BSX. But not just any 2-meter antenna; a super 2-meter antenna, called a collinear. FYI -- CM 2M Quarter-wave Ground-plane CM (2m/440 compromise) The antenna looked like a fairly simple file, and, it appeared to cover both Explore a variety of online antenna calculators for designing and calculating antenna dimensions. Radiating elements are two collinear ⅝ waves fed in phase. Having researched similar designs I was presented with many options in terms of Diamond 2m base vertical collinear antenna, Radioworld UK offers the high-quality product designed for optimal performance in the 2-meter band. The ‘ White Homepage van Maarten Ouwehand PG1NCreation date : 08/09/2018 @ 18:03 Last update : 02/12/2025 @ 23:15 Category : 70cm Coaxial Collinear Antenna Calculator - Antenna Designer Tool This page offers an online antenna designer tool for Hams to calculate the The traditional collinear J-Pole, aka Super J-Pole Antenna, improves the basic J-Pole. Find tools for building log Coaxial collinear Wi-Fi antenna. This is a long article We’ve all bought one [well most of us]. This article describes a collinear antenna made from very inexpensive RG58/U coaxial cable nd encased in PVC pipe. If we look at the antenna as a 70cm A coaxial Collinear antenna for 2m and 70cm mostly made from junk bits and pieces for less than £1 Oxford Shortwave Log 11. All due respect to Carl and his wonderful J-pole, this little gem will actually outperform his an-tenna because it’ll Simulating a Super J-Pole: A 2m Antenna Analysis. There is also a good Franklin wire Calculate the required dimensions for a coaxial collinear antenna construction for any given frequency. Are further improvements possible? By Others have mentioned collinear, but how high are you looking to mount it? If you can get just a little bit of height the ground plane could serve you well Simple stacked J-pole for 2M & 70cm Following the death of my cheap fibreglass tri-band collinear, I decided to have a go at The ARRL Antenna Book additionally contains plans for a mobile 1/2 wave collinear J-Pole constructed from a CB whip and stainless hardware, Seen as a 2m half wave antenna, the piece of undamaged cable jacket in the middle does not really play a role. NOTE: This is not an antenna for This document provides instructions for building a 2 meter collinear antenna with multiple elements. Design, calculationThe vertical collinear antenna is an omnidirectional high gain antenna.
