Re: Garmin long range antennas

There are several longer rubber duckys on the market that work. I have posted that in the garmin threads several times. I am waiting for another model right now. Once I get it tested will report on it. This will be side by side testing of several units in hunting and controlled scenarios. Not a I think thing.
You do not want connect the long antenna shown in this thread right to the garmin. That is why I said you need the portable long range base. Yes, then they save you some money. I have been getting a good replacement from Hong Kong. Problem is they go faster than I can buy them. Then it takes forever to get them via airmail.
Length is not always a good thing. It is if it is tuned or designed for the signal. Yet jsut because it is a longer antenna does not make it better. If that makes any sense. Diamond makes the RH205. Which is a lot like that one shown. Yet it is tuned for 2m like most stuff. So the stock antenna does a better job even though it is a bit longer.
Yes the digital signal drops off faster. That is why when explaining the difference to folk, and have posted it. The change we all seen when we went from analog to digital cell phones. Also why you may get a text message out and not be able to make a call. it all works a bit different.
The garmin comes out of the box on anyone one 5 base frequencies with 10 channels per frequency. I have posted this before as well, but here it is again.
151.820 MHz 11.25 kHz Id's- 0-9
151.880 MHz 11.25 kHz Id's- 10-19
151.940 MHz 11.25 kHz Id's- 20-29
154.570 MHz 20.00 kHz Id's- 30-39
154.600 MHz 20.00 kHz Id's- 40-49
You can change them at anytime. Notice the bandwith I posted. This is how there is multiple channels used on each frequency. Some companies are claiming more channels, but yet they still are using the same frequencies. They are just closer together. So you could have a 151.820, 820.1, 820.2 etc. Sure more channels but are they useable. NO!! Even stacking the Garmin collars in one ID range causes porblems. IE 0-9.
