Thank you

I am just wondering, will I need "tails" to hook the new antennas up since the ports are on the PCB?

If so, could you please advise which tails will be needed? Thank you in advance

Is that right? I thought with dd-wrt you could increase to power output to the antenna?

Not any further than it is designed to go.

The relevant point is the antenna has no effect on the transmit power of the router.

which product have you brought? and which router are you fitting them to? whats the struture in which its going to be used like? what are you trying to achieve?

And more interference from surrounding users as you will now be able to pick up more distant WiFi routers.

A smaller aerial will keep them below the noise floor and work fine as long as you're above it by a margin.

That depends what way they're pointing.

A higher gain antenna will pick up more interference from one direction and less from another. This is why directional antennas (omnidirectional antennas are really directional antennas in one axis) are used to reduce interference.

The same applies to legitimate signal from your own devices.

So the router doesn't output fixed power. Agree the router has a power limit but it can be adjuster beyond the design parameters.

I thought antennas only affect the gain and therefore impact the signal

Correct, but it can increase the ERP or effective radiated power which is more relevant in path loss calculations.

An omnidirectional aerial in an ideal world has a circular radiation pattern when viewed from directly above.
When viewed from the side, it's a circular lobe shape.

Can anyone advise me on which tails to get? The connectors are tiny

You are aware that tinkering with your Superhub in any way is in breach of the terms and conditions of your contract as one with holes in it is not acceptable if you have to call out an engineer for any reason.

Buy a N router and use modem mode much simpler.

you are aware the OP is tinkering with a D-Link 615 and not the SH ?

Then why not just fit some screw on 9db antennas instead, much easier as it gives extra range and speed in many cases.

[thenry]

because the OP has the rev. that hasnt got the ability to screw off and on antennas.

Not a nice router in that respect but I fitted 3 on my Edimax and it works fine, pity it is not that easy.
