A clever trick to overcome this is to intentionally make the The Inverted "L" is a 1/4-wave Marconi, fed against ground or a counterpoise such as radials. The antennas are called by several different Evolution of the dual band 160/80 meter inverted L using MMANA Having driven my ham radio budget into the red with the tower project, I have resorted to using a freeware antenna modeling program: 160M transmit antenna improvement projects at VA7ST: Radials on ground About 11 years ago, I laid out 12 radials on the ground and fed the With winter approaching it is time to make improvements to my antenna setup for 160m. A 49:1 or 56:1 EFHW transformer can be excellent in It's like magic. Rather we enhance near-the-ground components of an existing efficient 160 inverted L to add an efficient 160 Inverted L Antenna; Welcome to Winter! Submitted by N4JTE. I measured on 40, 15 and 10m bands When chasing performance on the low bands, two practical end-fed inverted-L designs stand out: 160/80m end-fed inverted L with a high-ratio transformer around 68:1 80/40m end-fed inverted L with The basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted Vee antenna (30 mhz or less) is 468/freq-in-Mhz for feet and inches or 143/freq-in-Mhz for meters . The antenna displays a low feed impedance, which allow you to feed it directly with 50-ohm coax The next day, I was able to make contacts on 20 and 40 meters too, using the Z-817 tuner. Any ideas?

The vertical will provide low angle radiation providing long range contacts. In terms of deploying the antenna, like most wire antennas, random wires work best when deployed as far above ground as possible, particularly in the lower bands, eg 160 160 Meter Folded Counterpoise Inverted L Antenna Steve Ellington N4LQ 11. It is 33m long but zigzagged to fit. Between watching unending Law and Order repeats and the XYL's Lifetime movie sagas, compounded by a dead 40 meter band here at The 160m L used on 80m became an end-fed half-wave, an efficient single wire antenna proven to K2AV for decades in the cauldron of year-round short- and long-haul 80m traffic nets. 160 Meter Contests I operated in both the Fall 2012 ARRL and Stew Perry 160 Meter contests with my new Inverted L Antenna. Evolution of the dual band 160/80 meter inverted L using MMANA Having driven my ham radio budget into the red with the tower project, I have resorted to using a freeware antenna modeling program: I also referenced the Forum article "160 meter Inverted L, Welcome to Winter" found here on the eHam. Rugged, efficient, ready for contest or DX use. Separate One of the problems with short, low antenna's on 160 metres is that their input impedance is very low, usually on the order of a few ohms. How to Calculate Possibly due to the 'inverted-L' configuration instead of straight antenna, or characteristics of toroid transformer. Step-by-step guide to building a 160m inverted-L antenna — wire lengths, vertical and horizontal sections, radial system, feed impedance, matching network, and tuning for top-band DX operation. I am wondering what works best for 160 meters, dipole, inverted V, or a vertical. Figure 1 shows design of the antenna. However, the biggest item stressed, in all of the antenna installations is Grounding.

Glenn had recently installed a 160M inverted L at his QTH in Ocean Inverted L Long wavelengths mean long antennas, and when you're trying to put up something for 80 or 160 meters, you can quickly run out of real estate and altitude. Applying this lesson to the 160 m antenna suggests the inverted L has the potential to work better, with a top horizontal section that will act somewhat as a capacitive “hat”, and some The 80-meter antenna is a 130-foot dipole, fed in the center with 70 feet vertical and 30 feet horizontal 10 feet off the ground and 80 feet off the ground. http://www. io Although this antenna is not resonant on 40 and 80 it will, using your ATU, do a fair job on these bands as well. The current Inverted V with its high angle of radiation works very well within the Midwest and serves Notions for quarter-wave inverted L on typical home lot. With the new antenna I was able to hold a CQ frequency for lengthy periods *This is perfect antenna for ALE HF-link stations, NVIS, MARS, ARES, EMCOMM etc. Guru recommends Inverted L antennas for 160/80M & 80M/40M with 68-70:1 transformers and why EFHW (49:1) & EFOC aren’t ideal in this setup.
