Does pointing the radials of a ground plane in a certain direction have any effect what-so-ever???
Like if I pointed one of the radials at Starface would I be more likely to reach him or should I use two and bracket him or does it make no difference at all???

There are 4 GP Radials to most all Ground Planes Antenna's that use or can use GPK,One for each direction, North,South,East and West But even tho You/We add the GPK to the antenna we have to remember it's still a Omni Dir Antenna, there for just adding the GKP don't make it work like a Beam antenna but say if I was getting S-7 without the GPK and then you added the GPK and I was now getting S-9 then they are doing what they say they do. But pointing one or two radials my way isn't going to make me hear you any better. Omni means signals are thrown 360°
Add A beam and point my way and I'm going to hear you lots better!!
Till next time

Sinker they do lower the angle but also changes the match i have played with thme in the past with limited results. |

I have heard that it is best to point the ground planes northeast, southeast, southwest, and northwest insted of north, south, east, and west. |

read this thread. look for tech 808 reply and read. "GPK for Imax 2000" It's about 10 threads down from this one. You will be looking for Tech808 bending the ears up on the GPK till the radials are at about 30 degrees. Lon/tech808 said it made his tx/rx better than just having the standard kit bolted on. When my kit gets here this week and I put the kit on I will be bending the ears up till the radial are at 30 degrees. Oh I forgot you have the Maco antenna. I guess you need to ask Lon about that one. I have an I-Max.

the radials dont really affect the direction of a signal, and bending any of them will only decrease their functionality. the job of the radials is to keep your signal up off of the ground.
if your antenna base is up 36' or higher then you really dont need them. (this is something i read somewhere, dont flame me!)
with the base of your antenna less than one wavelength above ground (36 ft. at CB freqs.) then some of your signal is shooting straight down into the ground. the ground radials will keep it up off the ground and help put them out into the airwaves.

Radials don't affect the direction of the signal. They cancel out return currents leaving only the radiating element sending out RF energy. So if you have a quarter-wave antenna at any height, you'll need radials. |
