Jumping signal

If you are on Sprint I assume you are using a 1900 yagi . Also do you have direct line of sight to the tower . If not you might be better off with an omni directional antenna . If you have line of sight and are you are using a 1900 mhz antenna you might want to consider adding a amplifier to stabilize things. One other thing , are there any microwave towers in the area ? if they are between you and the tower you are connecting to what you are describing can happen . Try aiming at another tower not in that direction.

Yes I have the 1900 mhz yagi, and I dont have line of sight, I live on a mountain lots of trees and there are alot of towers near me looking out my front door on the mountain but they over spray my house, I have my yagi outside back of the house. I was told by sprint that there are 2 towers near me, 1 being right about 3 to 4 miles other is about 6 miles out one being south east other south west, Just so frustrating the way one week I'm getting 1.5 download then next week I fight all week to get 400kb moving my yagi to new spots over and over, Just dont make sense why its so good then the wind blows and poof there goes that great signal you had for a week, Would it help to lower my yagi down from house is it possible IM to high to keep the signal?

My signal does stuff like this too. Like when the wind blows the signal jumps around, which is probably from the antenna moving in the wind. Clouds can also affect it, don't ask me how, but my signal will be worse on cloudy dark days.

But I'm also 9 miles away from my tower, through a hill kinda. According to google earth the antenna is level with the top of the hill. Then there's some trees to go through. So I kinda expect a poor signal. I'm just amazed it's as good as it is though.

And you don't want to aim over the tower. Doing so is probably just as bad as not aiming at the tower at all. If you think you are, then try tilting the antenna down a little. That is, if you can. And I wouldn't think lowing the height of the antenna would do much, but that's depending on how much above the tower you are.

if you don't have line of site you should try an omni directional antenna mounted at a decent height . You might see more consistent results.

If your sig and speed are jumping all over the place and you have several towers around you, as do I, then the problem really is that the device (you didn't say which one you have) is probably jumping from one pilot to another. You can watch this behavior in the DEBUG screen, if you know how to access that. If all this sounds like technobabble, just tell us what device you use and someone can point out how to view the DEBUG screen.

Having said that, I need to point out that some devices (Sierra589U for example) do a better job at discriminating between competing towers, and will lock to just one at a time, and others (like the Franklin CDU680) will consider two, three, even four different antennas as 'active pilots' which can destroy speeds quickly.

Sorry I almost forgot I posted this msg. I have 595u aircard, I just post new question, I bought a amp still having trouble and in debugg mode i guess the Pn is pilot you was talking about and it is jumpping numbers. Is that towers?
