Barry ...one of my other hobbies is N scale model railroading ..... I have tried 160m scaled down to N scale and it didn't load up .... Jerry .... I never tried 160m in HO scale so I am unable to answer that one but on the serious side I am lucky and live on 10 acres with no restrictions of any kind ...... I have full length 1/2 wave home brew wire dipoles running all over the place for 10m thru 160m ..... I run the antenna's thru a MFJ 993B auto tuner ...... and it has been my experience that loading 160m thru my 80m dipole gets me about the same results as I switch back and forth between the 2 antennas in real time ....... I figure that the lack of difference now is because of the poor band conditions .... one day I will raise the 160m dipole higher as I threw it up in a hurry to participate in a PODXS contest one afternoon years ago .....seems like I am only on 160m now for PODXS contests .......raising it is not high on my to do list .... hi hi I also have a Mosley TA33 at 40 feet ....... Zero Five vertical {10m thru 40m} and I can confirm that a vertical is noisier I use to live in a deed restricted subdivision in FL with ZERO tolerance for ANY type of antenna so I know firsthand what many of you are going thru and sometimes we have our hands tied as far as antennas go .... so we have to make the best of a situation that unfortunately requires a compromise .... Jerry is right about the efficiency of a antenna in regards to trying to make up the length electrically .... My father was a Ham for 70 years and I will always remember him telling me what good is top of the line radio with a bottom of the line antenna setup ..... He told make sure you have money for the antenna setup also ... JEFF WALSH W3WMU #1673 BUBBAWOOD WORLDWIDE HEADQUARTERS STURGIS, MS.

80/160m Antenna
Mike... You’re aimed in the right direction with the beverage. I had a beverage on 160m when I lived in So. 5-land... 817’ long, terminated in a ¼ watt, 50 ohm resistor about 5’ above ground...(whatever the top wire of a barbed wire fence is, agl) Many a time in the middle of a contest I had to put my “Bayou Reeboks”, (rubber boots) on and fight the critters and bugs to change that resistor ‘cause I x-mitted A L O T of power through it! Live and learn. One thing to look at is a 4-square, switchable x-mitting antenna. Doesn’t take acre’s of space and it works... Any antenna you build for 80 and/or 160?...Pay attention to the losses! I’m a true believer that it’s so easy to lose a db and dang near impossible to gain a db with the low power of the digital modes. I’ve discovered that if I only had privileges on the 160m band, there would a way to get something on the air... Steve, W3HF can tell you how far some intelligent ingenuity and necessity can go when it comes to antenna’s... Milt. n6mg 070-650 LONP #76 DXCC Honor Roll

As Jerry said… verticals ARE noisy.
I noticed someone mentioned an Inverted L. I love my Inverted L, but I’ll say that when I had my 160 meter loop, I would find myself transmitting on the Inverted L and receiving on the loop. Neither antenna heard better than the other, but the loop was MUCH quieter. Inverted L’s have a vertical component which contributes to the noise.
If I could only have one antenna , I’d probably go with the loop. It’d be a tough choice, but the sounds of silence are really nice when trying to pull out the weak ones.

There are some laws of physics/antennas you just can't ignore. An antenna that is a 1/2 wave length or longer will be more efficient than anything shorter. Sure you can use loading coil and such to make antenna appear electrically longer, but you still have an inefficient antenna... everything in electronics seems to be a trade off; you have to sacrifice one thing to get another. Just like in engineering you can build something better, but it may not be as good as what you had in the first place, but I don't know much about thatld. Did some tower work years ago and the crew tended to "over-engineer" things to err on safety side.
Anyhow, years ago a friend and I loaded up a 300 ft. AM broadcast tower on 160 in winter for some contest. Results were awful ... lots of noise and not many signals. Verticals tend to be noisy. Guess that's why some DXers on 160 use beverage antennas for receiving. Used to have a serious 160m station a few miles away which had 9 phased 110 ft verticals with a little tuning shack in middle. It belonged to K9DX and was operated remotely from his house 30 miles away; had a couple tours and it was awesome. All the hardware and antennas were expensive as well as the 80 acres of land it sat on. It gone now (sigh).
That was the ultimate DXers station and far out of most hams budget.
On the "poor hams" budget, some do quite well with limited antennas on 160m. Would suggest that you search for "160 meter antennas " on the web and find something that will work for you. A word of caution, ignore some of the claims made as every QTH is somewhat different with soil characteristics (soil conductivity, etc.) , height above average terrain, sources of interference, and so forth. Seems like some of the better 160m DXers live in areas where it's marshy near lakes, rivers and oceans... guess you could always flood your yard ?
Good luck !

I'll see if I can get a mark up of my plot from Google Maps or something, but let me see if I can explain it a little.
I have lots of land around me. Though it isn't mine. I sit on about .65 acres of usable space. I have no major trees (anything taller than the gutter in the front yard). My antenna sits on the back corner of my house. It is a crank up tower about 40' (aluminum) with a K4KIO Hexbeam on it. Works really well...I think, this is my first setup. But, I can do a lot on 20 and 40 (even though it isn't necessarily intended for 40m). I have a tuner in my K3.
Out back of my house there is a large tree. I could probably get something up in there and connected to the tower. When the tower is lowered it sits about 14' (not including the antenna).
I have hesitated doing anything with this, because I do not want that in my line of sight out the back yard, at least not when it is going to be down and drooping.
I know to be efficient longer really is better. But, I just haven't found a great antenna that seems appealing and easy to put up without a lot of headache and trying to make things work when I have no idea what I'm doing with antennas. I'm a mechanical engineer with focus on medical devices, and antennas are still black magic to me!

Re: 80/160m Antenna

I know what you mean about being less efficient. I guess the question is less efficient or nothing at all. That is where I'm at right now. I'll certainly dig into it more. I was curious what everyone here was using, sounds mostly like larger wire antennas rigged in their yards? There are 3 hams in Utah that have outrageous (and awesome) low band antennas. That are arranged in 4 corners, with many, many miles of radials, tuners, etc. They have excellent results. =) They all sit on around 5 acres or more as well. I love the hobby, and struggle with the antennas! Bryon, W7RIV

Re: WWWWIIIIDDDDDEEEE Signal
Roger Bryon-
Sorry for telling you what you already knew! Once set, the K3 setup just stays rock solid. The only control I fool with is the power knob when going from QRP to about 35w. I also have to play with the power when I go to the WSJT-X modes (don't need 35w!) but I don't have to fiddle with the sound card or computer settings. You probably read about my Rub Goldberg 160m antenna adventures in earlier posts just before the Great Pumpkin Sprint. It is such an outstanding antenna (only slightly better than a plastic coat hanger stuffed in the back of the rig) I won't repeat it here. But I will be most interested to see all the suggestions you get and to hear what you do. Hope I can go to school on your approach! 73, Rick - N7WE 070 - #1602

Distortion anywhere in the signal chain can cause a wide signal. That means the distortion can occur when strong, clean signal is received by a less then good receiver. …and a strong signal can be caused by a good antenna and good propagation — not just high power. Nobody ever said turn down your antenna. ;-) Another country heard from, 73 de Eric, KG6MZS
