The BARGAIN basement part 2

Anyone tried these? They seem to be all over Aliexpress now.

@ Epyon

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? :confused: 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

  • update - first impression = ok


10 dbi (90 cm) and 3 dbi (40 cm)
