Diy 2m 70cm mobile antenna. 8:1 across the whole range with a minimum at 446 MHz Hi All, I recently built a super simple and affordable dual-band 2m/70cm antenna using a PA0FBK design. A better design is to make a 2 . Plans, pictures and parts list. I read the article he was referring The operational frequencies for this antenna are within the VHF/UHF amateur radio bands; 2-meter band including frequencies from 144 MHz to 148 MHz, and the 70-centimeter band including Second the NMO2/70 for the taller antenna. » A good homebrew 2m/70cm antenna to build for on the roof. » 2m/70cm Mobile Antenna » Stacked dipole antenna » Wire Dipole Antenna Question. At you station at home the antenna can be mounted vertically in To better understand the type of antenna with two radiating elements with 70cm in a V, I built a simulation of dual bander with two V type radiators for 70cm and one Problem 2: Vague on Key Points Solution Provide detailed measurements so hams without SWR meters or antenna analyzers can build this exact antenna and have it work on generally-useful frequencies I enjoy building antennas. A fellow Ham recommended that I try building a 2 meter / 70 centimeter vertical dipole antenna. The best part? It cost me less than Build a portable or permanent dual band J pole type antenna. The YT clowns have probably never heard of antenna modeling. 4:1 and 1. If you're not fussy about 70cm performance, a 1/4 wave 19" whip on 2m will work on 70cm. Of all simple vertical antennas over ground, the 5/8 wave radiator has the lowest angle of radiation, however the base of the 5/8 antenna presents a relatively low impedance, not the high impedance This is Dual Band 2m-70cm J-Pole Antenna that can be “Rolled Up” and conveniently transported in you Go Kit and un-rolled when on site. » MAAS This is a simple, compact, and easy to build 2m/70cm Delta Loop antenna, easy to transport (it is just wire and a connector) and for attaching to a window or in tree The PORTABLE or 'BASE' 2m/70cm Copper-pipe "J" Antenna by N6JSX 08/2013 This is my revised "BASE" 2m/70cm Copper-Pipe "J", a "how-to DIY" with an Looking for a simple and affordable way to boost your 2m and 70cm ham radio coverage? Check out this DIY tutorial on how to build the PA0FBK dual-band antenna! Those work ok on 2 m but on 70 cm the radiation pattern is terrible. Looking for a simple and affordable way to boost your 2m and 70cm ham radio coverage? Check out this DIY tutorial on how to build the PA0FBK Step 8 – Measure SWR for 70cm (Optional) Sweep the antenna from 440 MHz to 450MHz – the SWR should be between 1.
