anyone built a 5/8 vertical for 10m
I looking for plans to build a 5/8 wave vertical for 10m. I keep thinking I will
find a old CB 5/8 to convert at some yardsale or fleamarket but havent so far so
and after having success building a colinear vertical for vhf now im ready to
try again. Im trying to pickup a local traders net on 28.375, most checkins are in a 40 mile radius, I added a 10m leg to my HF dipole but signals to the sides are very very weak. I could easily build a 1/4wave but my thinking is a 5/8 with longer element would receiver much better.
It just might. Try it and see.

Here's one for $80...probably not a bad deal considering the cost of aluminum.

I was given a Imax 2000 with the ground radials from a cb station that quit.
With just a bit extra ground wires it works fine on 10/12/15/17
Working that like years, so i can choose between the OCF and the vertical
Any cb 5/8 will work on 10 meters, just keep it a few inches shorter.

I knew a ham once who used a 5/8 wavelength CB antenna, a Shakespeare Big Stick, to work 10 meters and had good luck with it, working DX all over on it using a 25 watt Uniden HR2510. Of course, this was back around 1989 when the sunspots were higher than now. To answer your question, yes, it can be done.

10M antenna plans
Don't know if this helps you any or not but I have plans for a 10 meter J-Pole on my website. This is by far the best 10 meter antenna I have ever built.
Get the plans at http://www.kc0tks.org/index.php?opti...=103&Itemid=42

Thanks for the reply your 10m J pole
Looks like the kind of project I would like to try, the webpage has great closeup
photos. I had thought of a 10m J pole before but alot of post say you have
to isolate a J pole from all metal or it wont work. Guess you have actually done
it and it works so this maybe my project for the coming Holidays.
I've been using a Maco V-58 for about 4 years, two of which was on CB. It worked great for CB and when I shortened it for 10m, its working better than ever. I used to use it a bunch for ground wave, but it even works great for DX. I've never needed more than 100w, most of the time just a 25w HTX-10 will do the trick.
A local store was selling them for $65 back then, not sure on the price now, but I know they still offer them. Maco makes some fine antennas, and all aluminum construction. PM me for the local store number.

It does not work as good as i though (but it should outperform my 1/2 wave dipole also monobander for 17m) as the 5/8 vertical take-off angle is much more lower.
Anyway, i´m still confused about the radials sizes, i´m using 1/4 elevated radials (as the antenna is on the building´s roof).
According to software, the antenna will perform better with full wave size radials, also at 1/2 wave high.
I wonder if anyone has some experience or opinios regarding improving my homemade antenna?
It´s nicely matched with a tapped coil, it presents a low swr, but as we all now, this means nothing, even a dummy load will do.
I´m looking for good performance like 3.3dBi and around 16º angle elevation.
Cheers in advance,
