Digital TV Antenna
Digital antenna TV has to have capable reception on TV Band Digital TV frequency , from 470-862 MHz.
We can design with Yagi model, Logarithmic antenna Design , Fractal Antenna design or other design that proven can receive with good quality on this band. with frequency reception, we can design this :
862 - 470 = 392 , 1/2 Lambda will be , 490 + 392/2 = 666 Mhz
For Yagi antenna , I use calculation design from K7MEM.com

or you can also get design from Su and Chang http://www.jpier.org/PIERL/pierl12/14.09102302.pdf
The implementation looks like this :
I have tried the Su and Chang design , with good reception at Digital Terrestrial TV Channel and average quality in analog TV channel reception.
DIN rail ARM7 Ethernet/USB Subsystem (LPC2138)
- This package is ideal for industrial use, facilitating quick connection and relocation
- DIN rail mountable and compatible with OKW Railtec C-5 enclosure
- On-board BASIC compiler runs 30 times faster than interpreted BASIC
SUCCESS
Astronomy
A NASA astronomer selected ARM Ethernet controllers to create a one-off error-correction system for an infrared telescope.
Our secondary mirror
assembly would occasionally jerk. So we constructed a system using
eight BMA180 accelerometers, each attached to an ARMWeb SBC.
These were then programmed to acquire and stream the accelero- meter data to a Linux server. The server would save and graph the data in real time. When an 'image jump' was recorded, this accelero-
meter data was analyzed to help identify the faulty mechanism.

Today and tomorrow
we are demonstrating our Android controlled robots at GoogleIO in San
Francisco (perhaps the biggest tech event of the year).
The robots all use your Super Pro board. Your boards connect with the Android tablets via Bluetooth.

PRO Board 60 MHz (LPC2103)
SUCCESS
Monitoring
We use the ARMmite
Pro (predecessor to the LPC2103) to control a high-speed frequency
digitizer that we make for one of our products. It offers great
"pin-level" sensing and control, and can do ‘smart’ things like send the
data as serial, and it can be programmed quickly in a BASIC-type
language.
By orienting the design around the Pro, I can make changes in the device’s operation quickly in software rather than making hardware design changes, which is a much slower process.
