Hi
I purchased three NL-770R antennas of ebay a number of years ago fro China. Over time two of these failed due to the internal capacitor in the base breaking so I decided to order three more (this time from Singapore).
When the new ones arrived all three had excessive VSWR and were unusable. They looked exactly the same as the ones I had previously purchased. After some email ping pong with the supplier I was refunded for them by eBay.
As I was still after the antennas I ordered two more in two separate orders this time from an Australian supplier on eBay. These arrived this week. They looked the same as the others but used soft steel for the elements. They also were unusable due to excessive VSWR.
Existing NL-770R antenna VSWR 146 MHz 1.5, 435MHz 1.4
The ping pong game with the supplier has been started today.
Problem is I still need to source dual band antennas no longer than about 1M so they fit into the garage. I will just have to keep trying!
