Hi

New distance record in rough terrain with the garmin roof mount antenna is 14 km = 8.75 miles

What was the past distance record, I have gone 15 plus miles through rough terrain and across the valley's on a hound race. using my garmin hand held.

15 miles plus sounds

but was it summit to summit? Last record with garmin and cableantennas was 10 km in rough terrain.

How does one take a roof mount antenna through rough terrain? In my opinion if there is roads then it isn't ruff terrain. I started at the base of one mountain ran half way up then went along the side of the mountain before going over the top, down the other side 6 miles across a valley and almost to the top of the next mountain before getting treed,( after hiking over the top of the first mountain I had a friend go back and get the truck and bring it around to the next mountain, as i continued following the dogs, it was a 100-110 pound tom that was traveling, it took me half the day and most of the night to make it to the tree, in Nevada you can be a hundred miles from the nearest town and there isn't roads running through every mountain range.

Maybe I don't know exactly how this record system works, maybe I need to figure out how to carry a roof mount cable antenna, heck maybe I should........... I'll just keep chasing these Nike tom's and wearing out the tread on my boots.

Ok maybe we are talking about 2 different things here, after looking at some of your past posts I think you are talking about the garmin astro tracking system, your first post doesn't mention the astro, I was talking about a garmin gps.

There is no record system! but i have to learn you how to use the garmin astro :lol:

and it´s no big deal to carry a roof antenna in the backpack!! Look at a map and you will se that northern Sweden has lots of mountains and little of people. I live 150 miles from the nearest town. Why use the astro if you dont use the best antennas, my dogs are to expensive to lose during hunts. I dont use the roof antenna at all the time but now and then i make some test to see if the equipment will make it during a hunt.; but i always use my cableantennas and i think some of you are using them to :wink:

Best Regards BIG SWEDE

I live in Michigan and haven't had anywhere near the range you guys are talking about. Normally I can't get over 1.5 miles. Do you think lots of trees has anything to do with the poor reception? I have the roof mount Garmin antenna for the Astro 220. I just wish I could get 5 miles!

duster,

Think of the trees as columns of water, which in a sense they are. Radio waves do not travel well through water, so more trees equals more water equal less radio reception. Green growing corn is even worse than trees, they can be up to 85 percent water whereas trees are not usually more than 45 to 50 percent water.

Water (and high water content vegetation) will also affect a traditional dog tracking system. My traditional system gives me 12 to 15 miles line of sight, yet there have been times when I could hear the dogs barking in a corn field that was only 1/2 mile across, so I know that they were within 1/2 mile, yet I could not get a signal on them. I have noticed a similar decrease in range in the piney woods of Louisianna.

If you are not useing the modified antennas that bigswede talks about on the garmin thread on the dc 20 dog unit, try them. They definately gave me increased range over the factory antenna.

if you want more range I would buy A yagi or a loop antenna they will give you at least 3dB gain. Were as a dipole you don't get any gain. The MURS frequencies are 151 Mhz and 154 MHz so the antenna would be bigger than that of a 216MHz-220Mhz yagi so they wouldn't be real good to pack around. So you might try a Moxon or a Loop. The MURS frequencies will are real close to the 2 Meter HAM band so any 2 Meter antenna will work you can probably even find a 2M dipole antenna with more gain than the one Garmin is putting on the market.
