Replacement antennas for PCE-AC68

[Anosh]

I've been offered a PCE-AC68 but it doesn't come with the original antennas and I'm wondering if anyone knows what I can get that would be equivalent to the original antennas?

It would seem the antennas are simple omnidirectional 2dBi for 2.4 and 5Ghz.
A suggestion on another forum was Delock: http://www.delock.com/produkte/F_558_ehftechnik_891_5-8-GHz.html?setLanguage=en

But with the additional cost of three antennas the total amount would be around the same as the retail cost of a completely new PCE-AC68. In there words not worth it..

Also found an easy to understand explanation of the difference between a 2dBi and a 5dBi antenna:
