Can anyone tell me what is so special about this resistor?

[daisizhou]

What I know so far is that this resistor is installed in the high frequency circuit network,The current flows through this resistor to generate a voltage, which is supplied to the 50 ohm RF as a sampling voltage and supplied to the AD834.I only see the NWW10 imprint.
Welcome friends who know to tell me, thank you

Wire wound 10 watt 2 ohm at 1% is that not special enough?

It seems it also says 'non-inductive' here https://datasheetspdf.com/pdf/1345610/Stackpole/NWW10/1

Can I use DALE NH-10 instead of using it?

[abdulbadii]

the circuit demand its precise value as it is produced and intended to be an excellent accurate  low resistance values and high power rating properties

make sure replacement has that rating requirement

The Dale 10 Watt resistor is only rated at 10 Watts at 25oC.

It needs to be on a heatsink, the actual wattage it can handle is directly rated to temperature.
At 100oC it is rated 7.5 Watts.

What is this in? What is the resistor's purpose?

[Bud]

If the resistor is in RF path, you need a non-inductive type of resistor. What frequency range your circuit is?

NWW is non-inductive wirewound:

The DALE NH-10 is also non-inductive wirewound so it might work, but with the conductive aluminum enclosure I doubt it.
