Diplexers are quite expensive (about 10 € for 1pc). You can buy just antennas and cables to have 6 antennas together - two common for both 2,4GHz and 5GHz and 2 for 2,4GHz and 2 for 5GHz.
I have now 5 antennas with only two diplexers…
One question for @psiegl: Does the card have heat sink on it? As seen on picture of my AC wave 2 card, it came with pre installed heat sink. Or there is no need for heat sink?
That would be actually great. I had not seen the pigtail and antennas on discomp website but looked just briefly. I just bought new Turris Omnia at fair today and talked with guys from team. I asked them if they will be selling the kit for upgrade to wifi ax and they said they plan it but were unable to give any details or date so far. My plan is now to migrate from blue Turris 1.0 to Omnia. Actually it is going to be new configuration on HBD TOS 6 and do the upgrade to ax and switch once I feel it is ready.
OK, then it might be necessary to add an heatsink. I’ll add it to the accessory-list above.
Do you think, heatsink is necessary?
After all there is one gold standard for electronic devices - the cooler they are operated the smoother they run.
I don’t know how well the AW7915-NP1 is engineered (remember the faulty capacitors of the WLE900VX bundled with TO Indiegogo version that refuse warm reboots) and I’m tired of finding out the hard way so I myself clearly recommend using a heatsink.
Hmmm, thats true, but does that from discomp, recommended for LTE modem, have enough capacity to cool down this wifi card? I think it is the same as for CPU on Omnia, which uses the case for further heat dissipation.
So, then there will be one from CPU + 2 from wifi cards. If cards will be hot, the case will be hot too and it could affect whole system. Heatsink of my current wifi card has different construction, not connected to the case. Maybe it is worth to consider this.
Edit: Maybe this one should be OK: AMPUL.EU - Hliníkový chladič 28x28x20mm s teplovodivú
or this one AMPUL.EU - Hliníkový chladič 28x28x15mm s teplovodivú
You are right, but we also need to consider that there is low to zero air flow in a passively cooled housing. A while ago I had to test my second TO (because it is operating standalone in an allotment directly below a non-insulat roof that gets pretty warm in midsummer), where I attached the mentioned cooler to both a LTE-modem and a WLE900VX and did a stresstest with all components (5 GHz-Wi-Fi, LTE and CPU) and as a result got a pretty warm but not hot housing. But this might be too much when operating 3 AW7915-NP1-cards in parallel…
Maybe someone owning a card and a IR-thermometer needs to do some stresstests followed by temperature-measurements to see if a small cooler is enough. But my gut feeling is no cooler will be not enough.
Well, yesterday I was copying some stuff from my 2x 2,5" HDD NAS perk, sumultaneously via wifi and LAN (= each HDD was running) and router housing was quite hot - 43°C in place where cpu cooler is sticked. With 3 such coolers sticked not far from each other it could be much worse.
Anybody else willing to participate in our collective order?
I’d like to join you guys…
What info do you need?
Just send me a PM how many cards you would like to order and which country you are from for a beginning.
As soon as we are “complete” (maybe 1 more week waiting for other participants) I will ask for the pricing and come back to you for how to pay.
Just FYI, they do charge $35 for shipping with FedEx plus there will be VAT + Tax + handling on top of that.
So, our waiting costs money…
They have raised “standard” price from 60 to 80 USD and the sale price from 35 to 39,90,- USD. Bad news 
I just asked if we can get the old price ordering 12 pieces. Even if not I’d rather not wait any longer. I’ll send out details this evening.
Edit: just got the answer from the shop - better prices will only be granted for orders >500 pieces. Reason for risen price is the chip shortage…
Okay I would suggest to order it now and send us payment details so we can clear it and you don’t have too much invested in the deal.
According to heatsink, I have disassembled my Turris Omnia yesterday and the maximum height which should fit is about 18mm.
My WL1216 card has its own heatsink with dimensions cca 30x35x7mm, so commonly sold heatsinks 28x28x13mm or 28x28x15mm shuld be fine.
i ordered some pieces of AW7915-NP1, so will see how fast delivery is.
When did you place the order? Have you already received a shipping email?
For now only Order is in processing mail confirmation, do not have shipping details yet.
