If I add radials on the base of my tower, after adding all my current baluns, will I be able to reduce my noise level a bit more? Keep The Faith, Jim K9TF/WA9YSD _____________________________________
Jim, Not enough information from you to determine an answer. Is the tower a vertical antenna? Or does it support wire horizontal antennas, or beams, or loops, or ? Local noise is often picked up from
Jim, that tower comment should have said, "tower NOT in touch with the ground to start with". Sri, Stuart Rohre _______________________________________________ TenTec mailing list TenTec@contesting.c
If you improve your grounding system, you will always be happy that you did. To say it will or will not reduce noise requires knowing a lot more about the specific details of your setup. If there are

Ground is NOT a sump into which noise is poured. A connection to earth is NOT a solution to RFI or noise problems. The ONLY benefit of a connection to earth is lightning protection. 73, Jim Brown K9Y

The grounding system for a vertical antenna is often deficient. That's easily seen when the antenna SWR is low, but there's no matching network. The perfectly grounded vertical should have a feed poi
Maybe so, however the question was about adding radials. There is definitely more benefit from adding radials to a vertical antenna system than just improved lightning protection. Perhaps no reducti
Well now.... As far as radials go. I like to mount my verticals off the ground. Becouse just a few 1/8 wave off the ground. Is better than many in the ground. If I am not missaken. Some thing like 2
Sadly Derwin, you are very "missaken". Do a search on W8JI, or read ON4UN's Low band DXing books to learn how ground system really work. There is "no free lunch" with radial systems. 73 de Billy, AA4
With all due respect to W8JI and ON4UN, there has been a lot of more recent research done by commercial AM broadcasters over the past couple of years regarding elevated radial systems for vertical ra
Hi Ron, We are not that far apart ... the key is as you mentioned, "special design considerations" ... that's the important piece. Otherwise we end up with 'ham lore' that seems to think that 2 eleva
You know that many noise filtering circuits (for power lines, ethernet, RF and etc) use circuits the one half of which is connected to ground. Remove an effective ground connection and you degrade th

WRONG! This is one of those confusions we have about multiple uses of the word "ground." A filter does NOT in any way depend on a connection to EARTH to operate. What it DOES need is the connection o
OK will do some ck'ing. Hey whille we are on antenna's... Someone know where I can find some info . I am looking to put my 5/8 wave 10 meter gound plane above my TA 33m Mosley. And I dont want it red

Worked for me and my dad with a quarter wave vertical about 50 years ago. 5/8 wave is less picky about its ground plane. Or you could tilt the elements on the horizontal beam. 30 degree tilt costs ma
I need to know why some one said that adding radials would reduce noise on receive. You can view this on http://www.youtube.com/watch?v=J9a1mAAtSbE adds a different point of view of things. I have re
Derwin, I would agree with you as to not wanting to reduce the gain or change the TA33's pattern. But I am afraid that removing the radials from the 5/8w will make it worse, not better, unless you fi

Actually, radials are fairly ineffective for lightning protection. What works is ground rods. Last year I worked on an AM radio station that had a full 120 radial ground system at the base of it's to

Hi Mike, Intuitively, the radials provide a capacitive connection to earth, while the rods are part of a DC connection that includes both resistance and inductance. As frequency increases, inductance
Hi I worked at a college FM station where the idea was that a simple rod in the ground would be the only grounding. First storm, and the remote was taken out. With much effort, the chief tech convinc
