Garmin D-series Stub Antenna Review

Those that know me know I like to review 4 and 5 star items, unless it is totally junk and I long for the zero star rating. What was garmin thinking when they introduced this?
First - This is NOT a GPS antenna. The Dog collar has an embedded GPS antenna that works upside down while the dog is asleep with 4 bars - and its weatherproof!
Second - What this antenna does is shorten the 6" "rubber duck" antenna that comes with the transmitter. I have a German Shepherd Dog who has no problem wearing the 6" antenna.
Third - This is for VHF transmission (see my review of the external car antenna and the difference it makes from garmin) VHF is a lower frequency and needs a LONGER antenna - not a shorter one to work well.
So the product here is counter productive to getting range on your dog. Hunting dogs ignore the 6" antenna. Nobody goes hunting with a yorkshire terrier that would need a smaller antenna.
So why make it?
I don't know.
You loose range with this antenna versus the factory original - You'll need the car antenna to pick up the signal with this whimpy antenna. MAYBE if you are hunting in tall grass that snags the 6" you might give up range for low profile, but I don't see the point in trimming off 4" then having reception problems on your dog's location.
My advice - stick with the factory transmitter 6" stock unit and buy the car mount if your dog likes to run miles. Finally, this won't help with the GPS reception at all as those antennas are built in and sealed up.
I gave it 2 stars because if your dog only goes a few feet, then it will work. If your dog pushes a mile, you'll loose the link
I also gave it 2 stars because amazon is stocking the accessories and not making me go to some tri-state electronics slum to buy an accessory.
Many astro users will be disappointed by the drop off in range using this

Most of the time your dog will be nearby when hunting, but garmin made the exception knowing that you may have a quad runner or 4WD and the rubber duck will be woefully inadequate and kill off your range.
When I bought my Astro it was only doing about .3 miles in the CITY - I measured the power out of the transmitter and had to send it back for repair, which brought it to about .67 miles. That's with the unit in my hand out the window of the car to get a signal, so I bought this antenna.
Range is now 1.77 miles - almost 3 times what it used to be! and that is CITY usage - taking it to the country went well over 4 miles. If you use any sort of motor vehicle and let your dog(s) roam, this is a must to find them.
The fit and finish of this is very well done - it meets all my expectations and is designed around garmin's antenna interface.
I was surprised Amazon stocked this but very pleased they did. Recently alot of electronics have disappeared to outsourced stores off amazon making orders hard to put together without paying shipping for each item because 4 vendors get involved. Cudos to amazon for stocking the accessories that make a product SO much more useful!
