NE555 Chip Square Wave Generator: Adding Antenna for 8/33kHz Underground Locator Use

Hello.
Could an antenna be added to the output of this system, which would emit this rectangular signal into the ether? I have an underground installation locator that can work with an 8 or 33kHz transmitter. It is then possible to e.g. let the transmitter into the pipe and locate its route with a locator.
Greetings.

And this metal or ceramic pipe?

Metal detects but e.g. plastic. For example, I put a transmitter into a pipe that transmits 8kHz and on the surface, using a locator, I mark its route.

Read my question again.

Mainly plastic, but can also be ceramic.

My point is that in a metal (not to mention magnetic) tube, you can probably forget to target anything inside.

Yes I know about it. But as I wrote about the metal pipe, my sensor detects normally. I'm just wondering if, for example, by connecting the output of this system, for example, a coil as an antenna, it would have a chance to work? Would I detect with a sensor the signal that would send this system?

Вот тут аналогичное предложение.

Of course, you can connect the antenna to the NE555 output, but we do not know any technical details of your locator's operation and you will have to determine experimentally what the "power" of this transmitter should be and how exactly the frequency should be tuned. We don't even know if the receiver reacts to an electric or magnetic field, but I assume that using magnetic underground makes much more sense, so the transmitting antenna will be a coil. The NE555 has a current efficiency of 200mA, quite a lot, it will be easy to overload it with experiments done with a stick. Experiments could start with an audio power amplifier driven by a sine wave from the sound card - you could initially check the suitability of the coil and range, and then do something tailored on the 555.
What measuring equipment do you have?
