Attic Antennas

A little surge of discussion about attic antennas on reddit here and here.

I've posted it a few time before, but my setup:

Extra Work

KB6NU has a great idea for a job opportunity to help "cable cutters" setup antennas for their televisons:
"From a technical point of view, though, it’s not very difficult, there are fewer and fewer TV repair shops that do this work, and with the trend towards“cutting the cable,” you should be able to find plenty of customers."

Yellow Makes the Best Antennas

Other colors don't perform as well I bet.

Not sure what it is about yellow, but maybe I need to add a tag for it since I keep having yellow news and stories.

First, from Roberta X's trip to Dayton, I love the models in this picture. But wait there is more... they are functional for 2 meters! Check that link for other pictures from her trip. Also, hop over to her other blog for a look at some of her "key" findings at the hamvention.

Another antenna seen via @gregmalcolm on Twitter. Unfortunately, I don't have the infrastructure for a hair-tenna.

Nagoya NA-701 and NA-771 Antenna Changes points out some changes to the new versions of the NA-701 and NA-771 antennas. This might be a useful link if you are worried about fakes and want to compare old and new. Also, they mention the change addresses the cosmetic gap problem.

Inflatable Antennae

Inflatable Antennae... now, if they would just make one for an UV-5R we'd be in business.

Antenna Recommendation

Despite the tremendous price increase over the earlier recommendation, Hans likes what I am calling the $4.98 antenna.

He says:
"These antennas now replace about most others here. In some cases they don’t improve performance (Wouxun and Quansheng stock antennas are fine), but this antenna is sturdier than most. Please note that this antenna is only available with an SMA-F connector."

So, I'm not an engineer by education and I only have limited experience in ham radio, so the good news is I learn a lot when I take a few minutes to read something like the February 2013 QST.

In an article about how to hang wire antennas, I was introduced to the term catenary:
"In physics and geometry, the catenary is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends. The curve has a U-like shape, superficially similar in appearance to a parabola (though mathematically quite different)."
Of course, there is math to optimize the hanging of wires/cable. I just never thought about it beyond is the wire high enough that something won't run in to it and is it tight enough that it won't fall down in a few minutes after I let go.

Go Anywhere Snake Antenna

The Snake Antenna:
"It is not a 'miracle antenna', though some people might say it’s a miracle that it works at all. Some operators swear by it; other operators swear at it! But it does work, albeit via an ATU, and with the availability of propagation."

Deal Alert: Antenna for $3.71

From Hans (PD0AC):
"This seems totally wrong: a replacement antenna (SMA Female) for the Wouxun, Quansheng or UV-5R for a price that won’t buy you a decent burger."
He's not had it in his hand, but thinks it is worth the risk.
