Standard Link Amps exist at Rare and Very Rare rarity. Community studies estimate the Rare Link Amp's drop rate at approximately 1 in 500 item rolls. The Very Rare Link Amp never drops from Portals and is available exclusively through Passcodes.
The sponsored SoftBank Ultra Link is found at Very Rare rarity and adds unique effects to the equipped Portal. Insufficient data is available to estimate its drop rate, but it appears to be approximately 1 in 5 000 item rolls.
All Link Amps have 0 stickiness.
SoftBank Ultra Link[edit | edit source]
In addition to increasing the range to which outbound Links can extend, the Ultra Link increases the number of outbound Links that can be thrown from the Portal and adds 15% mitigation to each linked Portal.
Increased Max Outbound Links[edit | edit source]
Each SoftBank Ultra Link equipped to a Portal allows an additional eight outbound Links to be thrown from the Portal. This effect does not diminish like other mod bonuses, allowing up to 40 Links to be thrown from a single Portal.
Increased Link Mitigation[edit | edit source]
The Ultra Link applies a fixed 15% mitigation bonus to all Portals linked to the equipped Portal.  If the equipped Portal supports at least one Link, this bonus will be applied to the equipped Portal as well.
The Ultra Link mitigation bonus does not stack. Applying multiple Ultra Links to one Portal, or linking one Portal to multiple endpoints with Ultra Links, has no effect. Each Portal will receive the 15% mitigation bonus in addition to mitigation provided by the Links themselves.
Range Amplification[edit | edit source]
|* Range depends on the Level of deployed Resonators , multipling the standard range by the numbers above gives the amplified range|

Destroying Link Amps has no effect on existing Links. Existing Links outside the Portal's newly-reduced range will remain standing.
Strategy[edit | edit source]
The Link Amp's role is obvious - throwing extremely long Links to create very large Control Fields Δ. In practice, high-level Portals have Link ranges of hundreds of kilometers, and few Agents will ever approach the limits within their entire careers. More often than not, Link Amps are found deployed haphazardly onto low-level Portals as an Agent pads out their Engineer numbers.
That said, Link Amps enable impressive city-blanketing megafields, as well as blocking Links with hard-to-reach anchors. Often, the items can be safely deployed in all four slots, as the anchor's obscure location is protection on its own.
A popular prank is for two Agents to fill capture an enemy's favorite Portal, fill its Resonator slots with L1 Resonators, fill its Mod slots with Link Amps , then use a Flip Card to return it to his or her control. "Pineappling" or "Campfiring" the Portal leaves its owner stuck with an awkward, embarrassing, and largely useless Portal.
The Ultra Link Amp's special features enable some interesting gameplay possibilities. A single Ultra Link can grant extra mitigation to dozens of nearby Portals, forcing opponents to take it out first. Two connected Portals with a few Ultra Links each can enable just two Agents to throw a dense stack of layered Control Fields Δ.
Trivia[edit | edit source]
- The maximum length of a Link, using four Very Rare Link Amps, is 6 881.28 km, or about 17.2% of the Earth's equator.
- On 15. March 2018, the longest known link of 6 881.278 km was created from New Zealand to Easter Island, 99.99997% of the maximum.
