How far can you see???

Now that I have your attention....LOL

I just purchased a tracker maxima 1000/5 in 217 freq.

My question is this, I need a second collar.
with this unit what collar would give me the best range?
ie. Intello, Wildlife, Quicktrack, Marshall, Magnum Telemitry, Others

any input would be great... Pinpointing not so important, range being very important!!!

217 mhz

See which collar transmitter has the highest output power. At 217 mhz the best you will get is line of sight plus 30% if your lucky.

Thanks wayne...
is output rated in watts like a 2 way radio??

anyone else??

I got a friend who had a Marshall Stealth tracking system and he tracked dogs for miles and miles and miles and miles. It was AMAZING.


Posted by Wayne Valentino on 12-28-2005 05:59 PM:

it

should have a wattage rating or milliwatts .500 milliwatts is equal to 1/2 a watt... If you have a large antenna with multipule elements it will pinpoint the collar better than a small antenna. Being up on a hill gives you more of the horizon, i.e. line of site plus as much of the 30% as your setup will give you....

Wayne,

I like these boards cause you can always learn something new on here.

I am going to plead ignorance on the "line of sight plus 30%" and ask just why that is?

The reason I ask is that it seems I get much, much more than that with any system I have ever used (quick track, ATS, Tracker, don't matter). I am in the mountains and line of sight isn't very far here at all, but I have picked them up a couple of miles away pretty easy.

If you have the time would you please explain to me why it seems like I am getting much more than "line of sight plus 30%" and why that amount is all tracking systems are supposed to get?

Thanks.

line of sight

with regard to radio frequency can and does vary. Radiowaves can bounce off mountains go around bends ect. The general terms of line of site to the horizon plus and additional 30% of that distance tacked on makes up that general formula...i.e. If you have 1 mile to the horizon you can genrally expect a range of 1.3 miles. This is due to the curvature of the earth. The more elements on your yagi antenna helps in finding the most faint of signal from the transmitter. The antenna helps the reciever to be more sensitive... Being on a hill over water will enhance radio wave propagation, as water will also reflect radiowaves...

in addition

the signal generated by the transmitter is very simular to morse code in the way it is transmitted. A signal of this type "gets through" better than lets say a voice transmitter. This also enhances the effective range of tracking devices.... Any more ?'s.... Been a ham radio operator for a long time, just another of my hobbies,wife says I got too many...lol...

Thank you very much for the explaination. I knew there had to be some physics involved for it to only be "LOS + 30%". So basically it's the curvature of the Earth that limits the range?

Is there any one frequency that gets better range with less interferance, or is there any particular frequency that we need to avoid due to limitations and interferance? I have a 217 and I notice that in a certian range of that 217 (like 217.2 or something) it seems to pick up power lines something fierce (one of my collars is close to that range and it is aggravating). I have even picked up electric fences on it, so any frequency tips?

I saw

this also recently with Briars tracker while we hunted together one night. Any electric system that is causing a spark will create interference. Electric fences that are put up poorly, a bad insulator on a utility pole, ect. The higher the frequency the less interference you should recieve but unfortunatly a spark covers a wide range of frequency that is hard to get away from. Also the higher the frequency the less range you will get and it will be more succeptable to interference and degraded operation by foliage and other stuctures. The 217 mhz units seem to me to be a good operating frequency to use...

Longer radio waves

bend around curves more readily. So technically, the very low frequency (lower frequency= longer waves) systems work better where there are a lot of obstructions. Within the range of most systems--214-217 or so, the differences are too slight to make much of them. I have never worked with a system in the 150 range, but there are a few out there, and theoretically, they should work best. However, most receivers don't cover that broad a range, so you'd need a specialized receiver for them and you won't be able to track your hunting buddies' collars. All kinds of surfaces can reflect radio waves--water, leaf coverage, any metal fence. You can get interference from all sorts of sources--there's lots of radio waves from all sorts of objects, even stars. You have to know the local obstructions to know what will cause most interference. Wire fences and electrical transmission wires will cause interference at different frequencies depending how thick and how tightly they are strung, just like a musical instrument. Marshall has a pretty good explanation of the technical aspects on their site.:

This has been one of those threads that I actually learned something and did'nt walk away feeling as though I have listened to sheepster rant for an hour... Thanks for the great telemitry lesson... has anyone published a book on understanding radio waved and radio telemitry?? I would like to learn more... I will check Barnes and Noble, maybe they have somthing....

Ya'll stop!!!!!!!!! My brain cant handle all this new info. lol

Sounds like I got lucky. Not knowing anything about tracking systems when I bought mine I ended up with a 217 freq. Wildlife Mat. TRX1000. I have the 3140 collars.

check

www.arrl.org it is a ham radio site. look under foxhunting... It is where guys hide a transmitter and they go out attempting to locate it..Just a game they play to test radio wave propagation....
