What is the Best Base Antenna?

[ctvanover]

I know that it's probably been asked before but I want to know just what is the Best Base Antenna to be used with a Galaxy DX 2547 Base Station and maybe a Linear if I need one? Or maybe I'll just use a Magnum S-9 with the RX-75 installed as a base. Either way I need to know what the Best Base Antenna would be for me to use on either of these two radios.

I live in between two mountains, there's one behind me along with a set of railroad tracks that you have to cross to get to the mountain and one in front of me is probably 250 feet away from with a 2 lane highway in front of it. So what would be my best options to get out and over these two great ole big obstacles?

Any and All Help will be greatly appreciated!

How much money do you want to spend?

 

[ctvanover]

I don't know give me some prices, some ideas of what I'm looking at

For local there is nothing you can do to get over those mountains. For DX they'll make no difference.

In an ideal world you'd have a 200ft tower with four 5 ele or more yagis spaced at different heights where you can switch between them or combine them as required. You'd have a vertical on the house or nearby for local work.

Oh! Bummer, well thanks anyway! I guess you just saved me some money!

The only thing I can think of to add would be to setup a dipole and try NVIS with it, but I would not hold my breath.

 

[M0GVZ]

Its certainly worth a try. Make a dipole up and put it up about 10ft or lower. Make up some wires the same length as the dipole and lay them on the ground below it as follows - ignore the twin lead part, just make it from single wire.

nice description through figure.. now i get it with more clarity..

NVIS on 11 meters ain't gonna happen for him.

 

[The DB]

NVIS doesn't happen at CB frequencies very often, if ever.

They maximum frequencies typically used is the 40 meter ham band. It has been known to happen on 20 meters, but usually only near a sunspot peak.

To happen all the way up near the CB band would take some serious solar activity.

The literature tells us NVIS doesn't happen on 11 meters, but I tried an experiment that had me thinking otherwise.

I ran two 102" whips in phase 108" apart. Each was mounted on a marine ratchet rail mount on 10' long 1.00" plumbing pipe. I'd experiment with the angle of the vertical whips until I got them almost horizontal.

The experiment continues.

The best cb antenna is mine! I will let the second best go for a good price. I have it to lol!

 

[Needle Bender]

I'm gonna dare to disagree with the statement that 'locally you're screwed'.
I doubt you'll ever be a major CB Celebrity on the immediate other side of the mountains, but a 1/4 wave GP erected as high as possible will give you the highest vertical TOA I can think of, and just might get you a little performance

If local talking is you objective. Just try your existing antenna at different height with a station on the other side of the hill. I live right next to the San Gabriel Mountains on the Mojave side and for me the "magic" height was right around 20' to get over the 6000' peaks. At 110' I never heard the next valley. To many variables to give an kind of answer other then trial and error.
Try a beam.
