Check ebay for more selections from this antenna maker. I have a couple here for 2m/70cm and PMR and can say they are working really quite well for me.

Am I missing something, or is there no link?
There is no link as the seller had no more online. If you check this ebay number it is the seller so when he puts more online it will be on his time line: 291397926081
