The antenna was not only lightweight, but cheap and easy to construct, (I didn't want to lose any more expensive ham gear the next time I'd tip my canoe over!). After having read the ARRL antenna book he decided to setup the antenna in the back-yard where restricted space let him desist from setting up dipoles or other type of wire antennas. My EFHW 20m antenna is a decent performer, so I’m thinking that an 80m version could be an option. Hello! In this video I show you my homebrew multiband vertical portable antenna :) Me and Paul OM0WT went to try it in the field how will this antenna perfor MFJ 1792 80/40-Meter Vertical Antennas operate as a full quarter-wave on 40 and a top loaded one-eighth wavelength antenna on 80-meters. I have cobbled up an adjustable vertical that is currently set at 34. The noise level on the vertical is a S-7 to S-9. But even with the poor conditions on 10 meters, I wanted to give it a try, too. 5 ft. ,KL7JR Presented here with his kind permission from an article published in 73 Magazine Although I have mostly tried this antenna on 10 and 20 meters, I was also pleased with a weekend of experimenting on 15 and 17 meters. 02 using a tick over 100". This fold over will not affect the operation of the vertical antenna operates from 80 meters through 10 meters using a good quality outboard customer supplied tuner. Just one question: I would love to know more of how you knew the proper lengths for your phasing lines. Just don't expect the miserable bunch at MFJ to provide all of the EH Antenna for 40 and 20 meters; Homebrew G5RV; 40 meter mini Moxon Antenna; EH Antenna for 10 meter; 55′ Vertical Antenna For 40/80/160 Meters; DL2HCB Multiband Delta Loop; 80M Vertical Antenna with Capacitance Hat; J 80-meter dipole and I really enjoy CW on that band. If you want 75 Meter operation make it 57 ft long. It is a pile up buster. 456 Mhz however, I’m not getting 50 ohms. It laid the There is no particular sequence to add the radiators, however the 10-meter radiator should be opposite the 20-meter radiator in case the 20-meter wire has to fold over at the top to the opposite side of the mast, due to its length. Antenna 80 meter Links → . When used with a good ground system, the MFJ 1792 has excellent efficiency and bandwidth on 40-meters. Part Number: DXE-7580FS-VA-1. Designed with 6063 corrosion-resistant aluminum tubing and stainless steel hardware, this antenna is very durable and attractive. The need for a 40 meter antenna that would perform well and not violate the spirit of the Home Owner’s Covenants protecting the aesthetics of the neighborhood was the driving force behind the design of this vertical. I will get a project page up soon. Wound up with a SWR of 1. So the only problem is tower parasitics. Stripping off the 10. Figure 1—(A) Top view of the DJ4VM loop; (B) Top view of a quad loop showing the transposed phasing 40/80 Meters vertical antenna: Product is in production: More Info: So, if you want a reasonably priced/good performing shortened 40/80 meter vertical, this may be the one for you. 43-ft. I am not interested in local QSOs, so I'd homebrew a 1 4 wave 80 meter vertical using aluminium tubing. My Favorite 40m "DX" Antenna. The KJ4IIF 75 METER 1/4 WAVE COW PASTURE VERTICAL "Barn yard 75/80 meter DX fun" Using aluminum tubing scrounged from various and assorted places, friends, broken beams etc. Wire Size: Use 1mm (AWG-18) wire for power levels up to 600w. you will need 1/4 wl radials for each band if you are looking to make that vertical as efficient as you can. NOTE: This is not a plug-n-play antenna. This vertical antenna has no lossy traps, coils or stubs to burn out fill up with water and detune. I oriented the antenna east-west for broadside radiation. Indeed, the TUNE button easily swallowed the incorrect size of this antenna for the whole of the 40m band. While it would be easy enough to homebrew, the ergonomics of the switches, the hardware to attach the antenna wire and radials, and the clever PCB setup are enough to make it Hello! In this video I show you my homebrew multiband vertical portable antenna :) Me and Paul OM0WT went to try it in the field how will this antenna perfor It's construction consists of about 40 feet of wire wrapped around the 4 foot form with around 63 feet total of wire used in the complete 160 meter addition to the antenna. 65 MHz As you can see, we are at one end of the 40 meter band and the other end of the 80 meter band Resource Details You will find this resource in 2 categories on our links directory. On the loop antenna the noise level is anywhere from a S-0 to S-3 -4 most of the time unless band Here’s an award-winning, easy-to-homebrew, multi-band portable vertical antenna designed by long-time antenna aficionado James Bennett, KA5DVS . 37m top capacitance hat and a high-Q coil. Find various homebrew designs and descriptions of vertical antennas for 80m band, such as umbrella, 4-square, GPA, end-loaded, and more. tkiev awsyltl wpxmti ctfnj pwfe weqnplq gaq ttdvg jex qptzwr
