	Most jammers have a maximum effective range. Therefore, another way to counter jamming is to simply outrange it. This can be achieved with most long range radars, such as the [[component:rs41-spyglass-radar \|RS41 Spyglass]], [[component:r550-early-warning-radar \|Early Warning Radar]], and [[component:r400-bloodhound-lrt-radar\|R400 Bloodhound]].

	Most radars will be able to produce a line of bearing (LOB) toward any jammers that are affecting the radar. Jamming LOBs will remember the last range to the ship that is doing the jamming, provided a track on the ship was held within 30 seconds of when the jamming started. This LOB range can be updated via crossfix, briefly regaining the track, or burn pings. Time-fuzed shells can base their timing on this last known range. While the accuracy of this Jam LOB varies from radar to radar, and is rarely accurate enough for gunfire or other dumb weaponry, the LOB is still useful for quickly responding with counterfire, whether it be RPF/Bombshell, missiles, sending jamming back at the enemy, or just knowing where to close in. LOBs can be crossfixed via strobe correlator.		Most radars will be able to produce a line of bearing (LOB) toward any jammers that are affecting the radar.

			Additionally, the purple LOB produced by the strobe correlator can be locked by a ship's FCR, unlike a normal red jamming LOB.

	Jamming only works on active radar sensors, and therefore sensors that don't need active radar will be unaffected, such as visual range (roughly 3km around every ship) or ELINT systems such as the Pinard. Despite being operating in the radar band, Pinard cannot detect jamming.

	~~[wip]~~		ELINT detectors (such as the Pinard) allows a ship to passively detect enemy radar emissions, such as those from search radars or fire control radars, but not jamming emissions, at up to 1.25x of that radar's max range. One ELINT module will show a rough line of bearing toward the emitter, while two will produce a crossfix. ELINT will also be able to identify what type of radar it is (or more specifically, it can reveal the ELINT category of the radar) and will display it on the ELINT LOB or crossfix. If the ship is equipped with multiple types of radars, the track will display all detected types.

	Finally, friendly ships outside the enemy's jamming cone will be unaffected, and can easily spot the enemy formation and relay those tracks to the team automatically. As such, jammers provide a very powerful incentive for teams to spread out. A team spread across a wide area is much more resistant to radar jamming compared to a team that is tightly grouped, and is a method available to all fleets without needing to take one of the expensive tools listed above		Finally, friendly ships outside the enemy's jamming cone will be unaffected, and can easily spot the enemy formation and relay those tracks to the team automatically.

Radar illumination works in the game by painting targets inside the cone and increase their return power. Illuminators work similarly to jammers when it comes to calculating power on target over range, but instead the power is used to boost return power for all radars (search FC, and missiles radars). It is often used as guidance for SARH(Semi Active Radar Homing) missiles, but can also aid in radar searching and locking.
