Big Wires - A 160 / 80 / 40 Meter Multi-band Antenna. Top Band, as 160 meters is called, presents a a challenge because the long wavelength leads to large antennas. One can always play tricks with loading to be able to use a physically shorter length of wire. There are many articles on compact 160 m antennas, but this is not one of them.The 15.0 major release is coming up! This version brings many exciting improvements to GitLab, but also removes some deprecated features. Visit the deprecations page to see what is scheduled for removal in 15.0, and check for any breaking changes that could impact your workflow. By signing up...counterpoise length for end fed antenna. Note that any of these lengths are going to be long on 6 meters.Here we take a look at an End Fed Half Wave antenna which is resonant on many HF bands due to a 49:1 matching unit being used.Posted date: August 09, 2021 in: Antenna.The end-fed feature adds convenience, and makes it very portable.If you're lucky your coax feedline is the correct length to ... good enough. Remember that one S unit on your S meter is equal to 6 dB. At HF the difference between a 2:1 and a 3:1 SWR is virtually undetectable. As you can see from the above dimensions you don't need a massive lot or a small farm to erect an end fed wire antenna. One can install an end fed wire in an attic or even on a small urban lot.Buy Multiband Hf Antenna and get the best deals at the lowest prices on eBay!
