Until then design the antenna for a 1% lower frequency and inform me of the. The discone is most seen as a receive antenna but is under. Al Legary VE3SQB. Free Online Engineering Calculator to quickly estimate the geometric Size of the Parts of a Discone Antenna.

Antenna technology is constantly advancing to meet the growing demands of industry. Likewise, Remcom has been keeping pace in order to provide engineers with antenna analysis software that matches their processes and helps them meet their design requirements. Our customers’ interests range from simple academic examples to the latest cellular devices containing multiple antennas and hundreds of components. Models can be analyzed in for efficiencies, dissipated power, SAR, radiation patterns, reflection coefficients and more. Plus, using XFdtd as your embraces parametric analysis and exploits the computational power of GPUs. Additional Information Examples.

Haier Cg220 Unlock Software. I have been getting into software defined radio via RTLSDR and found the stock antennas woeful for reception and picked up a tonne of noise from my LCD and laptop – though it’s hardly surprising. So to improve the situation and spend as little as possible I decided to make a discone antenna.

After some research I happened upon VE3SQB’s site and a neat discone design program for Windows. Gta V Full Version Utorrent. As a compromise between frequency and unwieldyness I settled on 130MHz as the lower bound. Discones are inherently wideband and I expect the antenna to be useful for reception in the 60MHz to 1700MHz band the E4000 tuner can work with. The ingredients, all from Bunnings are: • 1m of40mm PVC pipe (my lust for PVC in making antennas is unabated) • 2.5mm galvanised tie wire • A 40mm endcap • Some masonite packer • 1.5cm brass washers • Stripped solid core ethernet cable From Middy’s Electrical Wholesaler I bought: • 20m RG6 quadshield coax cable • A bunch of F crimp type connectors (just crimped them with my pliers) • F to TV/Belling-Lee adapter With no test gear I have no idea what the true parameters of the antenna are. All I can say that it has massively improved the reception on my EzyTV dongle for VHF and UHF transmissions in conjuction with placing the antenna in the far end of my backyard.
