Anyone tried these? They seem to be all over Aliexpress now.https://www.aliexpress.com/item/868MHz-high-gain14dBi-omni-fiberglass-antenna-base-antenna-868MHz-outdoor-roof-monitor-antenna-free-shipping/32691472854.html
buying 2 pieces is interesting, free shipping to the Netherlands.
There's a new 3dB 868 antenna from the same seller, just came out for sale today. Looks interesting. $36.99 with free shipping
@BoRRoZ That's interesting! The only thing I wonder is why that length? You can make a collinear array with the same gain and much smaller dimensions (e.g. the Sunhans one).
the 10 dbi is 90 cm compared to the 14 dbi that is 150 cm
