What are you asking how to operate the transmitter or how to operate the transmitter at a distance, i'll take it you want to operate the transmitter at remote location away from your studio so you protect your studio equipment if your going to operate as a 24/7 pirate radio station.
You can link from your studio to the transmitter site with a broadband audio link or microwave link or use both this will protect the studio and the dj's, so when you get your transmitter confiscated you just replace the transmitter/ link receiver and your back on air.
Organised pirate radio stations normally have spare transmitters ready to be switched on as soon as one is taken off air, you can expect to loose transmitters on a regular basis, it's a game of cat and mouse.
The aareff equipment is expensive for what it is, this equipment was designed by steve the original owner of veronica in the early 90's before he went on to own and run nrg kits, steve updated and impoved the dsign of the equipment.
The equipment been sold by paul at aareff are designs that he took from steve and have never been updated or improved since he fell out with steve as he does not have the knowledge to design his own gear or update the designs of the equipment he's selling.

The only problem with being "untraceable" is that the government agency uses a tool that tunes into the frequency and finds the direction that it's coming from. If they chose to confiscate the equipment, you're SOL. As for the white noise idea, I like it.
400 watts a lot of power and is pretty likely to draw a lot of attention. I was using the 30 watt on a J-pole and I managed to reach 60 km straight (at least that's as far as I heard from)
Your topography is fairly flat so keeping an antenna hidden may be a lot easier.
As far as acceptable content goes all I can say is don't insult the government. patriots are more likely to report you.
Only thing about the white noise deal is people wondering why their radio stopped on a frequency with the stereo light lit up and hearing white noise!
24/7 op is not going to be easy to hide. As long as that signal is radiating, it can be traced and triangulated even with a basic radio with an S meter and a simple map from a telephone book.
Hiding a 4 bay dipole antenna system to produce 4x gain means those bays will have to be 1/2 wavelength apart from each other's ends, a phasing harness and main feed line. Not exactly something you throw up into a nearby tree or typical tv antenna pole. Your gonna need a sturdy ham tower at least and mount that antenna system at least 75 feet up (center of radiation) so a 120 foot tower would do.
Good luck!

There's no point broadcasting white noise as others have said if the transmitters on it can be traced thats why you need to use a 10gig microwave link and a broadband link to keep your studio safe and seperate from your tx site, using this way of linking makes it very difficult for them to trace it back to yourself, you only loose a tx and satcan, these are quick and easy to replace and your back on air....happy broadcasting

i have had for a long time the idea of multiple low power fm tx's on a single frequency synchronized and scattered throughout a metro or suburban area. they could be solar powered and license free microwave fed. you would use a point to mp ap and use p2p on the clients.
this creates plausible denial to any agents of the government snooping around.
a cheap pc can be used on the endpoints running linux a stream decoder, and some free processing software.
they would have to track down and shut off each site
my guess is especially if these sites are hidden in the woods they won't bother unless you are causing real RF (not financial) interference to a licensee.
just an idea i had thought up long ago. maybe early 2000s.

I thought about one like that, too. Use WWV or WWVB to sync the oscillators for perfect zero beat, hence no weired phase effects at the discriminator (let alone a messed up stereo subcarrier)
