Can you recommend a comparable router with removeable antennas. I want to use a couple with biquad antenna to distribute wifi 400 foot.
With TP-Link, any of their routers that end with a D have detachable antennas. So the comparable model to the one I posted would be TL-WR841ND, like so: http://www.canadacomputers.com/product_info.php?cPath=27_1046_365&item_id=062754
The transmit power on these routers is 500mw (27dbm).
The biquad antennas are very interesting. I see they have a pretty directional beam, 50 degrees for the single biquad, so good for point to point or for wifi coverage in a specific direction. For my long range point to point wireless networks I usually use 15dbi Yagi antennas ($40!) attached to THESE powerful 800mw (29dbm) access points. If my customer has the cash or it has to go super far I can buy WiFi dish antennas up to 30dbi.

It's difficult to recommend a router specifically because there are so many options. I recommend you find the hardware you like and then check its compatibility with DD WRT. I only buy DD WRT compatible routers now because they are so versatile. If you need something special you can upgrade it with new features. It makes them more future proof.
I would never recommend DD-WRT when using it as a wireless repeater. I've just had too many issues, too poor performance, dropped connections periodically, etc. when using DD-WRT for this purpose. Gargoyle is based on OpenWRT and I think, because it's way simpler, is a better solution to DD-WRT in most cases (more stable, better performance).

I personally love my ASUS RT-N16. It has 3 detachable antennas and is DD WRT compatible. I believe it can do what you want even without a firmware upgrade.
It can't do wireless repeater on the stock firmware, needs DD-WRT. It can do Router, AP and client bridge on stock firmware (way more then most routers!). I usually use the RT-N66U for most of my customers, but if you argued that the RT-N16 is the best router on the planet you'd have no arguments from me. Now if only it was $20 ;)

Thanks so much for the info. I will check out the Yagi antenna.
I have two old direct tv dishes to make the biquads is why I elected them. And I chose to do two because I want optimal signal/performance.
this is my situation.
20+mb wifi from comcast that I want to broadcast ~400 feet. Clear line of sight between antennas.
At the source:
modem & router in basement where cable comes in
two wireless devices at this location.
hard wire to second router with antenna to broadcast.
At receiver:
Antenna with repeater, one hard wired device and broadcast wireless
hard wire into house to 3rd repeater to broadcast wireless to 5 devices.

I'm an amateur radio enthusiast with a particular interest in antennas and low power communications. I have found a good antenna can do wonders. When dealing with low power good antenna connection wires are critical. The cheap wire they sell for routers can be so lossy they defeat most of the antenna gain. Keep in mind antennas don't actually increase power or sensitivity they just shape the radiation patterns. With wifi weaker signals = slower connections.
You might find this interesting. They have done what you plan to do on a much larger scale.

This was previously discussed and I believe the consensus we came to was no for the Obi202. There have been changes to the firmware since then.
Have a link? Thank you

Here are the Yagi antenna's I use: http://www.l-com.com/wireless-antenna-24-ghz-12-dbi-stainless-steel-yagi-antenna-7in-n-female

If you're using a dish (with biquads) on each house they will have to be aimed and aligned perfectly, because the beam is so tight.

400ft is not hard to do. If you wanted to do it 100% professionally you could just use a pair of outdoor weatherproof access points like so: http://www.newegg.com/Product/Product.aspx?Item=9SIA0AT0AE4516
I've done a pair of those at 3000ft and the speeds were amazing. They come with the PoE power injectors too!

two wireless devices at this location.
hard wire to second router with antenna to broadcast.
At receiver:
Antenna with repeater, one hard wired device and broadcast wireless
hard wire into house to 3rd repeater to broadcast wireless to 5 devices.
So just two houses? How I would do it:
House 1/source house with cable internet connection. Only 1 router required (not 2 like in your design), plug the Ubiquiti AP into the router and mount the AP to the outside of the house (set in AP mode).
House 2/receiving house, identical setup. Mount another Ubiquiti AP (set on client bridge mode) on the outside of the house and run a wire from it to a router (if you want them to be on the SAME network as you, i.e. you can share files/printers then plug the house 2 AP cable into one of the LAN ports on the house 2 router, not the WAN port, and disable DHCP. If you want them to have a separate network from you then plug the AP into the WAN port and make sure their routers IP address is on a different subnet then yours, i.e. if your router is 192.168.1.1 then make their router 192.168.2.1). You can connect as many extra routers in this house as you need (if it's a large house/difficult wireless penetration). If connecting additional routers/repeaters by a hard wire/ethernet cable (which is ALWAYS best) then disable DHCP on this repeater router and plug the ethernet cable into the LAN port on this repeater router, not the WAN port. You can obviously do wireless repeaters (like in my original post) in this second house as well. DON'T ever use access points for indoor stuff, they suck, always user a router instead (disable DHCP and plug ethernet into LAN not WAN).
If you wanted to get super freaky you could make the house to house link run on 5ghz, as not to cause any interference to the wireless networks in either house, and also so the point to point AP's receive less interference themselves: http://www.newegg.com/Product/Product.aspx?Item=9SIA1EA0MV8153
