Re: [Elecraft] Inverted L for 160 meters

Why not model it?  It would be very easy to do using the free version of EZNEC that comes with the ARRL Antenna Book, and you'd be able to try various combinations (like the fact that you could probably get away with just one counterpoise wire like I do) to see the effects. 73, Dave   AB7E

Re: [Elecraft] Inverted L for 160 meters

You probably should get acquainted with Rudy Severns, N6LF.   (https://www.antennasbyn6lf.com/)  He has written more than you ever want to know about vertical antennas, More specifically to your case, are you planning the radials to be elevated?  If so, they need to be the same length, in

Re: [Elecraft] Inverted L for 160 meters

Kevin,     Your instincts are right on. But, to answer your question the  radials do not need to be 130' long, but it is better than a shorter set. The inverted L represents a 1/4 wave over ground and needs the other half, the radials. But, here is where it gets a little tricky. 5 radials

Re: [Elecraft] Inverted L for 160 meters

Kevinr, I have an inverted-L on 630m (that is 475 KHz) and is simply a vertical section with one horizontal section. A quarter wave vertical for 1.8 MHz would be 137-foot high so 80 foot is going to be short. The horizontal wires add capacitance to the top end of the vertical effectively

Re: [Elecraft] Inverted L for 160 meters

If you are going to go with buried radials, I don't think 4 or 5 of them is going to do a very good job for you. Like N7WS recommended, look up N6LF's work and read it carefully. Seriously. 73, Dave   AB7E On 8/25/2020 5:31 PM, kevinr wrote: I have to be very careful of raised wires on

APF is not a cure all. It is an alternative to narrowing the bandwidth to the minimum to try to improve the signal to noise ratio. If there are strong signals near the one you are trying to receive, from a crowded band or DQRM, then it isn't going to help. If the band is reasonably quiet

[Elecraft] Inverted L for 160 meters

From what I can find, and what I can calculate, five wires, each ~130 feet long, could make a nice inverted L for 160 meters.  One leg for the vertical and horizontal portion of the antenna.  Four legs for the counterpoise (ground plane).  There are many broken wire antennas stored in my shed

Re: [Elecraft] Inverted L for 160 meters

Two reasons why I want to use an inverted L.  One) it fits my property well.  Two) I have never tried one before. I currently have an extra long doublet.  I can't remember the exact length but seem to remember over 120 feet for each leg.  The tuner on my K3 just won't match it below 2:1.0 so

Re: [Elecraft] Inverted L for 160 meters

I use a L for all HF band . One wire going up about 60 feet then goes horizontal about 85 feet or so. I use a somewhat equal length elevated radial about 10-12 feet off the ground. I use a couple of auto couplers, depending on the radio . A Icom AH-4 for my Icom radios and an SGC 230 for anything

Re: [Elecraft] Inverted L for 160 meters

Kevin,     Be careful when doing these comparisons. A 1/4 wave over a ground plane unless it has a really good radial system may not be as efficient than your inverted L. What I would normally suggest is an A/B test using signal strength at the receiving station, but that has it flaws also,

Re: [Elecraft] Inverted L for 160 meters

Good gracious. Why does everyone overthink 160m? OK, maybe just because it's fun. I get that. But as to operation, I have one (1) antenna, and it is a 360 foot EDZ (dipole) cut for 3.5 MHz. It's great on all bands, 160 - 6m. No radials needed. Specifically I worked 47 of the 50 states in

KD5ODS is not over thinking anything. He is on the right track, an inverted L is a much better top band antenna than a low all band horizontal wire. Kevin just needs to model his inverted L, he might be a little surprised to see which way the pattern skews. John KK9A Lyn W0LEN Good gracious.
