A couple of years ago I remember using two websites on my ancient obsolete windows computer. One to calculate the direction and distance in degrees on a compass from one place to another. And another was a mapping website that shows the projection of different antennas from your base location and allowed you to select different variables such as a vertical antenna, Yagi with 2, 3, 4, or 5 directors, etc. It then showed you on a map how far it would project.

I have found out what the first website was for the directions which is called Earth Directions dot Org.

The second website I am having trouble finding. Perhaps it wasn't a website after all and was software? I am pretty sure it was a website though.

If anyone knows the name of the website and can help me find it I'd appreciate it so I can add it to the bookmarks on my new computer as I am thinking about building my own antenna.

I loaded up my old computer system but can't seem to find the second site.

Hi John,

I did in the past use the online coverage calculator by Roger Coude - VE2DBE :-

https://www.ve2dbe.com/english1.html


The results were quite close to the sort of coverage I was getting with my homebrew VHF/UHF antennas but not entirely accurate. Pretty useless with propagation effects though being a line-of-sight/ground-wave coverage type of calculations.

I think the reason radio still fascinates me is that Mother Nature can be a fickle cow and you won't really know how an antenna performs until you actually build it and put it on air. Even then you'll never be 100% sure with changing conditions.

My own piece of lawnmower lead strung around my loft still surprises me with contacts on HF around the world despite protestations from more 'experienced' Hams of "No! No! No!" Wink

Even my first UHF beam was built by trial and error rather than calculations moving around and trimming elements until my field strength meter and VSWR looked good enough. Certainly works and although probably not an 'efficient' way of doings things I definitely had a lot of fun with it! antenna - Antenna Range Map 1f44d

(Get yourself a NanoVNA if you can, damn handy bit of kit for such stuff finding mine invaluable after being graciously donated by a fellow Charlie Tango member!)



Enjoy yourself with any antenna constructions you undertake as it is all interesting stuff.

It doesn't have to be all expensive or 'exotic' materials either, I've utilised old mains leads, steel washing lines, garden parasol rods and any other junk I can get my hands on for a bit of experimentation!


All the best,
Victor

Hi Victor.

I just wanted to say a big thanks! The Roger Coude site is the one I used previously. I managed to do a password reset and get back into it and find all my old templates.

John
