Part 2 - Ham Radio Antenna Radials




What do you think about this video?

SoCals Preps: I just bought one of these antennas after dealing with a comet rotatable dipole ... I have very limited space for radials, and an HOA to boot. having to get creative would be an understatement. thanks for the video

Delivered0ne: If ever you do raise it up to at least 15' and have your 4 elevated 1/4 radials per band, I believe you'll appreciate the lower TOA and additional 3dB gain.

Blaze1024: A ground rod at the antenna base won't significantly impact noise when its in addition to ground radials. What will eventually generate a lots of RX noise is using stranded wire for ground radials.. As moisture wicks into the wire corrosion forms throughout the entire length of each ground wire.. This corrosion will create millions of diode junctions between the individual strands of wire, Thats why you should always use sold copper wire for ground radials. 20-18awg magnet wire works great

PaintmanJohn: Greetings de KG5RK Looks like you have had this antenna in service for a while now. How about an update of the antenna? I've read some people assertions that it should be up higher. Some people have commented on your radials as well. So tell us. Does it pass the test of time? My reason for all these questions ... I just found one at a ham fest ! :-} 73

honeybees1: Is your antenna so close to the ground for testing purposes or do you intend to use it at that hight?

Blaze1024: I hate to say it but the DX engineering radial plate is really over priced antenna bling. First it's made out of stainless steel which is a very poor choice for a ground plate. And it's a flat plate, remember we are dealing with RF and skin effect. There's also going to be a dissimilar metal problem in the fasteners. A better system is to attach a 1 foot diameter loop of 1/4 inch soft copper tubing to the base of the antenna with the radials wrapped and soldered directly to the copper loop

redman840: I sure wish I could push the wire staples in as easily as you were able to at my location.Near Tucson,the Sonoran Desert is rock laden and the ground is about as hard as can be found.My first antenna as a Novice was a Hustler 4BTV.It worked quite well and I really liked it.Your install is done properly.Thanks for the nice video.Good luck with a very good antenna!...73...Dennis W7KB.

Channellock12: How long does it take for the grass to draw up the wire? Reason I am asking is what happens if Mr.lawnmower shows up. I am just saying. how tall before you mow?

n3ite: For those of you in a region where snow fall can measure 6 inches on the averag you may want to raise the insulated base to antenna feed point up offf the ground about 12 inches just incase it happens to snow...

Blaze1024: Unfortunately I see there are still a lot of myths floating around regarding ground mounted Antennas.. His ground mounted vertical with at least 30 radials will perform better then it would at 15 feet with only 4 elevated radials. At 15 feet those radials would still be well within a 1/4 wavelength of the ground and thus still coupled to ground with the same ground loss's. At 15 feet he would need the same number of radials to reduce the ground loss's as he would if it was ground mounted..

kd5exr: What did you do to prevent corrosion where the radials (wires) connect up to the grounding plate? If you didn’t do anything to protect the connection than I recommend a compound like NO-OX (it is nasty stuff so use gloves. Also, did you run a ground rod? I would be interested to know what the difference in your noise floor is with and without the ground rod. Thanks for the great video.

n3ite: great great video ... also like the technique when you wrap the radial over the lawn pin and then pin it in place... had not thought of that ... would like to work your station some day...

hamradiocrazy: @honeybees1 Yes, the antenna is installed permanently in the position where you see the it in the videos. I wonder why do you ask? 73 de WE5I

qn1010: "this wire will not be seen again" - I would like to add, unless one doesn't have a dog that likes to dig :-)

hamradiocrazy: @honeybees1 I see. Well, a vertical can be installed either way. Raised in the air, there should be at least 2 radials per band, and they must be carefully cut to resonance for each band. Elevated radials work very well, but pose certain mechanical challenges. On the ground, radial length need not be tuned, but for top performance they must be as many and as long as practical, with 32 radials being an accepted point of diminishing returns and .2 wavelength being an accepted minimum length.

honeybees1: @hamradiocrazy I see numerous videos of ham operators go out of there way to get there anetenna as high as posible,thats all.
