3 Element Beams
3 Element Beams
I think I am getting a set of these & a Tower.
What do you all think of these beams????? any tips??? :D

It wont transmit or receive any better than an iMax 2000!
Been there done that!
If you want a beam get at least a five element and then you will start to see the kind of performance you expect to see for all your money and work putting it up.

Interesting. I'm guessing there was something major league wrong with the 3 element. Every one I've come across would bury an omni.
Just my $.02.
And I would lay odds on you being correct.
The Beam will "blow away" an single driven element element dipole even if you discount the forward gain factor of the beam, there is the front to back rejection of unwanted signal thus giving you a huge advantage of being able to work stations who are way down in the noise for the omni users
Unless of course the "omnidirectional" antenna be a multistage colinear.
Try making one of them for 27 megs

Checkout a three stage co-linear
big gain omni but hooooge and I mean hoooge.
Practical and really effective for higher bands (VHF / UHF)
but at 30 meg and down, dimensions get stupidly big

Yeah you can say that again. Basically all they do is squash the radiation pa tern of an omni making it reach out longer. At CB freq they don't lend them selves to a manageable size, and a 3 element beam will do just as well or better, not to mention front to back ratio.Hamayar wrote:RoadWarrior242 wrote:Yeah I'd like to the engineering behind a omni base antenna that will out do a beam.

Been there done that!
ROFLMAO...
a 3 element will be good, the more elements the better,
but surely an Imax 2000...lol...
they are a glorified antron, a 5/8 fishing pole..who you trying to kid..
get a simple 5/8 silver rod and it'll beat an Imax..!!!
if you believe whats said about antron and Imax's, you own one..
if you know anything about radio you have a metal antenna..!!
It wont transmit or receive any better than an iMax 2000!

umm yes it will! with a beam you can fine a weak brodcast and turn your beam its way to pick it up and bring them in better you can't not do that with a A99 or imax and yes metal antenna's are better than fiberglass

Alot of skipshooters use horizontally polarized antennas. But the problemChickenHeart wrote:

with skip fading is that the ionosphere randomly changes the polarization.
But if you only want to talk to local mobiles, a vertically polarized antenna (like the imax2000) is your best bet. Somebody using a horizontal beam to talk to mobiles i'd think aint gonna get good results.
i was googling and found this neat resource for 11meter antennas: [Please login or register to view this link]
The radiation pattern is much much better on the flat side so you'll see more gain on the antenna. In DX the signal is constantly flip flopping, so sometimes stations with vertical antennas will dominate your radio, sometimes flat will. A simple test will show this. If you have a flatside beam and a vertical beam or a ground plane and you have them on a switch, when you hear somebody fading out on the flatside switch to the vert, odds are the signal will be fading in. When it fades out on the vert go back to the flat and more than likely it will be fading in.
