Good commercial made is not expensive.

Once you done with buying cable (pigtail) and plugs your concoction would not be that much cheaper and Not as Good.

Because Hi Light looks Ugly.:thumbsdown:

Like this. So I use Capital instead as a mean to Soft Emphasize.

It is my own Shtick not necessarily following the English rules.😉

In top of it I have a moderate form Agraphia.🙁

A waveguide antenna is pretty effective depending on the range you need. With proper line of sight, I have been over 2000 ft in range. Pretty inexpensive to make also. If you need signal over great distances, then a parabolic antenna would work, but be more expensive, and you would still need line of sight.

I've made a few waveguides - the best one uses the cardboard tube from a whiskey bottle lined with foil. When making them you must keep all dimentions within milimeters (like less than 2 milimeters...) of spec or you won't get the performance you expect.

This is a reflector made from cardboard and aluminum foil. It goes over an existing antenna and gives you a few dB extra. This is not good enough for mile-long runs, but will make a difference if you already have a marginal connection. Now, if you put one on each end of the link...

**EDIT**
I re-read your post. This is not the best design for a laptop. However, if you have a problem area in your house (garage, back yard, etc.), and you have a router with two antennas, this might be good to go on one of them.
