Replacement antenna for Buffalo WHR-HP-G54?

Have a question or want to start a discussion? Post it! No Registration Necessary.  Now with pictures!

Threaded View
Due to a slight accident which knocked the router off the desk, the
antenna is broken.  Anybody know where to get a replacement antenna?
I didn't see anything encouraging on the Buffalo site.

Usually the hinge section breaks & it will not stay in any position or
just hangs by the internal coax. The antenna is still functional as
its just a short piece of coax inside the plastic cover.
Anything you can do to create a "splint" to hold it in the position
you want would work. Just don't use metal as a splint.

If it is normally bent 90 at the hinge, maybe you can cut a couple
pieces of plastic (clear pepsi/coke bottle) into a "L" shape (1/4-3/8"
wide) & wrap/tie them in place (with string or ty-wrap), one splint on
each side of the bend.

Now to answer your question:
I believe you have a Buffalo p/n WLE-AT-NDRHB antenna.

Any short 2.4GHz antenna with a rp-sma connector would work.

I found this link but I dunno nothing about the seller:

WLE-AT-NDRHB High Gain Omni-Directional Antenna

$20 or so but it is the cheapest I could find searching quickly.

enjoy :)

It's fairly difficult to destroy one of those antennas.  Here's a
photo of the guts of a similar antenna:
<http://802.11junk.com/jeffl/antennas/coaxial/slides/coax-ant.html
As long as the guts are still together, and not ripped apart, the
antenna should work.  If the outer plastic or hinge are broken, just
glue it back together.  Otherwise, reinforce it with shrink tube, soda
straw, or something that's RF transparent.  If you're not sure if the
tubing is RF transparent, put a piece in the microwave oven.  If it
melts, find something else.

I have a WHR-HP-G54 on my equipment shelf.  The antenna is a 2dBi
vertical colinear, with an RP-SMA (reverse polarized SMA) connector.
There are plenty of those all over eBay and various shopping sites.
Literally any 2.4GHz antenna with an RP-SMA connector should work.

Search eBay for "RF-SMA Wi-Fi Antenna".  For example:

How's $2.69 including shipping from Hong Kong sound?
(Hint: Buy several in anticipation of the next accident).

Thanks to you and Kim for the replies.

The very bottom of the antenna has a brass-colored fitting
that screws onto the router base.  The plastic which
normally houses that fitting has broken, and about a third
of it is missing (can't find the piece).  So now the fitting
itself has fallen out.

It's hard to see how that fitting was electrically connected
to the rest of the antenna (actually - to the rest of the
swivel base), unless it was just pressed against it and held
there by the molded plastic.

I suppose I could try to superglue or epoxy the fitting back
in place, but I suspect neither would adhere to the plastic,
and I don't know whether the electrical connection would be
very dependable.  But at this point I guess it wouldn't hurt
to try.

As your comments suggested, when I just stack everything
back in place and brace it so it doesn't fall down, it still
works.  But that would leave it it a pretty delicate
condition.

Now that you guys have provided the technical specs, it
should be easy to get a replacement that works if my repair
attempts don't work.

Thanks again.

The connector is just pressed into the plastic of the antenna housing.
The only electrical connection is where the connector is crimped to
the coax. All the plastic parts are just to hold the little coax
antenna in position.

I've got an antenna that broke where the rp-sma connector is pressed
into the plastic & it is missing about 1/2 (or 180) of its support.
Now it's held in place with a small ty-wrap, to what is left of the
plastic. As long as I don't drop it, its fine.

These antennas tend to break easily but at least it saves the
connector on the AP :)

Oops. You actually never specified which router.  But yea, the
Buffalos I've seen, the WHR-HP-G54 and some of the WHR-G54S came with
4 dbi it seems.

- wrap it in electrical tape to stiffen it

- build up some hot glue or silicone or epoxy putty around it.  Bubble
gum would practically work!

You'll run into a spare RP-SMA omni pretty soon anyway.   They outlast
the devices and/or get replaced with higher gain antennas so they tend
to accumulate.

One thing to note:  Your particular router came with a 4 dbi, not the
typical 2dbi.  So you are better off fixing it or getting a similar
one.   If getting keeping extra 2db matters in your situation.

On the other hand, if you have  marginal connections, you could get a
small directional panel antenna for it instead.

Hyperlinktech.com aka lcom.com has a number of reasonably
priced choices. I have a number of their antennas.
