Wormholes

Maybe some ECM. Couple guns. Scram neut.

Seriously you are safe. Highly unlikely anyone is going to kick you out.

That's what Chinese POS manufacturers do!

Definately go for a large tower. I personally perfer Amarr for the extra powergrid. x6 of each ECM type at least, probably more. At least 6 small turrets, and then go mental with the mediums. If you're really serious about staying, add in loads of extra offlined guns and ECM, ready to be onlined as the others fall. Attackers really hate that! Be sure to space them out to avoid area damage getting them in groups, and have them all around to cover all the potential attack vectors (top, bottom, left, right, forward and back). Be sure to have some webs and scrams in there to stop them from doing hit and runs!

Personally i wouldnt recommend dampners or neuts. Though the neut can be extremely effective, its large power requirements means its often better to just have more guns.

There are plenty of examples of this Death-Star style setup to be found via Google. Best of luck.

Large tower, lots of ECM, some nuets webs and some arty's. having a POS gunner or 2 is a must. But as said, only time you C4 POS is going to get jumped on is if you really **** someone off, they really not that popular. You better of in the C2 side of that then you can farm the connecting C4. Even being in a C5 and not running the capital escalations if you can't is better if you have the numbers. C3 is better for smaller groups. My experience anyway.

Yes, but it's still a lot of work to keep ships alive.

OP: Basically what everybody have said; Amarr Large, lots of ECM but not without guns (mostly small & some medium) and scrams. Fill in the resist-hole with hardeners. Resists to 40% is enough.

Don't underestimate the scrams, when some scout starts to jabber about taking on a POS, thats the second question I ask; how many scrams? Get 3 of those at least, it forces any fleet to at least manage to kill some mods or sacrifice ships each time they try. Without scrams it does not cost anything to try. Too much ECM? Just warp out. Scrams forces fleets to commit.

Having one neut, one sensor-dampener and one web online also give a attacking fleet more parameters to juggle. The advice of "a little bit of everything" is a good one, but focus on ECM since its very effective, not to say OP, in C4s.

Do NOT anchor torp/cruise-batteries (makes you look like you don't know what you doing) or large guns (no dreads in there anyhow).

Do NOT have capitals floating visible. They are only a reason to go after you. They are in no way a deterrent. The knife that kills you is the one you did not see coming, keep them fitted but docked.

This.

I dont get why people think lower end whs are safer when it comes to not losing your pos. Two Step provided numbers that showed the same number of POSs are removed in c2s as they are in a c5.

The best thing you can do is jams, jams, jams. Throw in a scram or two and some guns and it'll be a big pain in the ass. That said, if you are relying only on your pos to fend off attackers, then you are going to lose it.

I recommend at least 4 large guns as they have range, and alpha. If you have no large guns it's possible to park 150-200 off a tower and snipe the guns with most of the group semi-afk. Also it's amusing when someone sits in a frigate "out range" from our POS, and gets poped by the large guns.

PS- Also remember to avoid grouping things tightly or you risk bombers or smart bombers taking out the group.
