Hello i was try to find any topic for planet structures with cloak and what is the max cloak on the planet,but I could not find anything.
So is any one can help me with list of all cloak structures?
Thanks

Sorry to sound rude, but you obviously didn't search hard enough. A simple Google search (galaxy legion max cloak) and I found two threads that laid out exactly what you wanted.

Most of the posts on those threads deal with max "passive" cloak. And nowhere did I see what the actual maximum cloak for a planet is. Some numbers around 3k or 5k and such is all. Although I did just skim through those so I might have missed it, but I thought I'd post here with an example. And keep in mind, this planet is not done yet either. I can still increase the cloak even further.

Colossal Plasma planet:
Passive Ability
Attack 100
Defense 700
Cloak 2050 (Obviously this can be increased quite a bit)

Legion Bonus: 120%

Planet Structures
Zolazin Void Tower Cloak: 100
Modified Grid-Pylon Research: 2, Defense: 200, Cloak: 125
Dark Anti-Beacon Defense: 500, Cloak: 150
Adumbrate Station Research: 1, Artifact: 1, Cloak: 200
Adumbrate Station Research: 1, Artifact: 1, Cloak: 200
Ergosphere Filter Cloak: 150, Cloak: 20%
Silthion Gas Vesicle Research: 2, Cloak: 150
Dark Pylon Shifter Defense: 400, Cloak: 90
Klorvis Shroud Generator Research: 1, Cloak: 200
Resonance Inhibitor Cloak: 250, Invasion Defense: 500
Polaron Emitter Research: 1, Cloak: 100, Cloak: 15%
Chron Shifter Cloak: 300
Meta-Tuned Jammer Research: 2, Cloak: 25%
Klorvis Shroud Generator Research: 1, Cloak: 200
Chron Shifter Cloak: 300
Isolation Bureau Mining: 2, Research: 2, Artifact: 2, Cloak: 400
Litheor Core-Tunnel Mining: 3, Cloak: 23%
Spy Uplink Research: 1, Cloak: 40

Add some Inverse-Flux Satellites Cloak: 800 each, and I have a total cloak of 20,804 before the legion bonus. 45769 after the legion bonus. It'd even still be 40k + with only 100% legion bonus.

And if your going to do the cloak thing, I recommend making sure it's unscannable, meaning that even with max scan nobody could possibly scan it. Although keep in mind someone could still critically hack you and get lucky to get the location of that planet. Max scan is somewhere around 30k or so, but I'm not sure atm. But this should give you a fairly good list to work on, even though it's not all inclusive.

Keep these in mind,

Ergosphere Filter, +150 cloak, +20% cloak
Cross-Signal Restrainer, +30% cloak
Meta-Tuned Jammer, +10% or +25% cloak
Polaron Emitter, +100 cloak (?), +15% cloak
Litheor Core-Tunnel, +15% or +23% cloak
Anti-Grav Repulsor, +15% cloak
Tejiar Ally HQ, +5% cloak (2:1 AP mod)
Ryelis Analyzer, +5% cloak (2:1 AP mod)
Roathir Listening Outpost, +5% cloak
Ventar Field Collapser, +10% cloak

You can also use Clandestine Revisions from LM market to boost passivle cloak past 4k, these are unlimited
I advise against that, since the badges are better used on omiforges.

Mods that give decent passive cloak and also give AP:
Scruuge Calibration Chamber, 200 or 400 cloak
Adumbrate station, 200 cloak
Alarri Comm Tower - P3, 350 cloak (2:1 AP mod)
Isobureau, 400 cloak
Uldri Spacial Folder, 300 cloak
Upgraded Quantum Accelerators, 300 cloak (2:1 AP mod)
Silthion T-Plasma Vesicle, 300 cloak
Upgraded Silthion T-Plasma Vesicle, 600 cloak (2:1 AP mod)
Ardyne Transfer Conduit, 400 cloak (2:1 AP mod)
Litheor Deep-Phase Prove, 150 cloak (2:1 AP mod)

You only need to get to 30k cloak or so to stop those without protogrids from scanning it.
You will need about 35k cloak to stop those who still have protogrids from scanning it.

Thank you for all the information

I think the current max scan including protogrid is a little over 30k. But very few players are scanning with that much, so 25k cloak on a planet is reasonable.
