A quick digression: Ever wonder what the "t" in stands for? The answer is "Telekom" because the company is a subsidiary of . Curiously, I have always found German products to be of high quality with good customer service, but for some reason T-Mobile is different.

Anyway, according to T-Mobile's mapping service I should have a signal strength of between three and four bars. Judging from my very precise measurements (that is, looking at my phone), reality is a little different, with my signal usually between zero and four bars and alternating between those states on a roughly 5-minute cycle. So far I have not been able to find an explanation as to why the signal strength should wobble around so much -- perhaps you have an answer and would care to enlighten me.

Actually when I write "between three and four bars" I should qualify that with the phrase "until two weeks ago." These days the cycle has shifted so now about every 5 minutes I get four bars for about 30 seconds and nothing, nyet, nada, for the rest of the time. Can customer service tell me why? No. Can they do anything about it? Hah!

So, with my signal strength wavering with wild abandon there was a great opportunity to see if a product I had just received could improve my service. The product is the , an external antenna for cell phones, PDAs or any other wireless devices that operate in the cell phone bands.
