Scalar Antenna

This is why we experiment I'm guessing im gonna have to find something or make something that goes that high. Also radio waves are just magnetic fields and electric fields so by using the caduceus coil you are removing the magnetic field aspects making eletromagnetic longitudinal waves

If you want something inexpensive that covers 112mhz, you might find a "spy type" very small low powered radio transmitter that covers 88 to 112mhz, its worth checking out..Why is 112 mhz important to you? ..

The AD9850 goes up to 125 MHz, but you'll need a microcontroller to use it. For an easy way to control it, you can use an Arduino.

Is the AD9850 a radio transmitter? ..

No, it's a DDS signal generator. You'd have to add an amplifier, antenna, and whatever else is necessary to transmit a signal.

Unfortunately its just a sine wave audio generator, not an RF generator...Thanks for the try ..

No, an audio generator would only go to 20 kHz. The AD9850 goes to 125 MHz. Big difference.

The AD9850 ive looked at goes upto 55mhz and costs £38 from Ebay...Mullac wants a CB Radio which is a radio RF transmitter, the AD9850 is not an RF generator, check it out for yourself ..

It's still RF, just not as high as what's his face was seeking.

Its not RF, it digitally creates very high frequency sine and square waves, that are audio waves...Take another look tomorrow, and see where the alcohol clouded your judgement

I'm admitting I was wrong about the frequency range, but dang... What do you think is the minimum range for RF? Do you think RF isn't made of sine waves? Haven't you heard of Fourier decomposition? I don't have to be right here. Go on and be the winner here. lol
