lon and bruce
do you use a wire antenna on cb?
i have been thinking about it and it could be tuned up on 10 meters too also i believe a g5rv woula work from 20 up to 11m

the only ones i hear is on either 19 and what they call low 30 = 26.5880, i think that is it.
i am disabled and can't climb and the wire would be better for me albeit it would be horizontal, and most skip is on the flat side.
I too love ssb, and a lot better than a.m.(anchient modulation)
my experience is there are a lot nicer group the ssb. Around here in adrian ga. every body thinks that vertical is all the configuration there is.not me there is a lot less noise on the flat side, just me i guess

Willie,

Sorry but I have never built or used a wire antenna.

Maybe Bruce will read this and post some helpful information for you to use.

Willie,
Years back (1970s) I put up a wire antenna, a 5 bay colinear for a friend who lived in an apartment. We ran the antenna in the crawl space under the apartment so it was about 2ft above ground. In a space of 3 months he had worked over 500 stations including 50 or so countries.

A wire antenna can work well. Give it a try.

For dx it can work very well, but for local work you'd have to get it up high and build a groundplane system.

I've made a longwire antenna before but was only strung between 2 T-Posts. It worked for DX but not aswell as my vertical.

I have an 'inverted-V' wire dipole in my attic as well as a vertical (Antron A-99 at present) mounted outdoors. The inverted-V works quite well considering that I have a single story ranch style home and the center feedpoint is only about 15 feet above ground.

I have made numerous local contacts on CB with it as well as DX using it on 10 meters. The inverted-V configuration sort of gives you both vertical and horizontal characteristics as well as being more omni-direction than a horizontal wire. If the inverted-V was your only antenna, I would mount it outside and get the center as high as you can and it should work just fine.

I can't speak for the the G5RV since I do not have one, but I do have 2 Carolina Windom style antennas up (one a 160-10M mounted flat, and an 80-10M mounted as a sloper). Both will tune 11M and anywhere in the HF spectrum, but I would say that an inverted-V cut for the 11M CB band would outperform my longer multi-band wires.

Willie,

I am not sure this will be a lot of help, but might help you make up your mind.

I have a 160 foot longwire at my home in 'L' configuration. It works wonderful for receive, but for transmitting, the higher you go the worse it works. Mostly because of the length making it directional in some directions and having deep nulls in other directions. On 3500 kc., it is very omnidirectional, but on 28 MHz., it becomes a nightmare. If you kept your wire short, it will probably work much better than mine.

a g5rv used on any band but 20 meters is a compromise. That antenna was designed as a gain antenna for 20 meters and 20 meters only, everyone just tunes it up everywhere else thinking its the best thing since sliced bread, but it aint. However, it works, just not as well as most people think it would considering feed line radiation and losses due to heat.

Goat, I don't know about that. My old G5RV beat a 4 el yagi into New Zealand on 6m. The yagi was at 60ft and the G5RV was only at 10ft.

There is a lot of additional information that needs to be taken into account before making such a blanket statement.

Having said that, of course any shortened antenna is a compromise no matter how it is electrically lengthened

this is true 237...however, my statement that it was designed by "G5RV" as a 20 meter only antenna is fact...its like they say that you have to have the ladder line portion of the feed line as vertical as possible, it is only true if you use it on bands other than 20 meters....why??....feedline radiation...and since when is that EVER a good thing...right?

but...those who use them love them, and those that dont like them never will.

i also dont see how my statement was a blanket statement...well, kinda, I was and am still saying just what you have said, all non resonate antennas (shorter or longer) are a compromise compared to a resonate radiator....therefore...according to its design...a G5RV non any band other than 20 meters is a compromise...simple fact....thats what it was designed to do.
