If you have the Standard, you have to have the antenna mod kit specifically made for the standard. The reason is the frequency for the Standard and the controller that transmits the control signal is 5.8ghz. The others all use Lightbridge on 2.4 ghz for both control and fpv display, except the P3 4k, which, like the Standard, also uses 5.8ghz for control signal. If you use an antenna made for 2.4ghz on a transmitter that uses 5.8ghz, sending to a receiver that is also 5.8ghz, you will suffer range reduction and possibly damage the final output power transistor in the controller.
Also, these antenna mods, most all of them, are highly directional. It is necessary to have them properly oriented pointing at the aircraft for them to work. If the aren't, you will lose signal at very short range. All these modification kits are a variation of the same theme, they rely on a specifically shaped reflector behind the antenna to focus and reflect the radio signal in more or less the same direction, much like the reflector on a flashlight directs the flashlight beam. The only exception to this is using a brute force power amplifier to increase the actual power of the transmitted signal. These setups are normally omnidirectional, so you can point them wherever you want and still have a much stronger signal.
That being said, if you have a Standard that is giving you over 1 mile in usable range, first, go to any casino you want right now and get busy. You are on a massive win roll. Dji claims only .6 miles for the Standard under optimum conditions. Six tenths of a mile or 1 kilometer. Most users report significantly less.
Here is a little more information you did not ask for, but I will post it anyway. The stock antenna for all of these aircraft, Dji or otherwise, is basically just an antenna wire with a connector on one end that plugs into the r/c inside on the motherboard. On the working end, it is just that same wire with the insulation and inner braided shield stripped back to a specific length, depending on frequency. This is what is inside the plastic antenna on the controller. The end of a piece of wire. The plastic part does nothing but hold the wire in place. It is in no way directional, except that it obeys the normal antenna rule of not working well straight over head. The modification kits like dbs and Argtech merely make that piece of wire extend out of the controller far enough to be routed in front of the reflector which is really the heart of the kit. That is all there is to it. The ones that use a copper reflector are really just an added cost gimmick, as any metallic material that reflects rf will work more or less as well as any other. This includes aluminized mylar plastic, as used in the emergency survival blankets. You could sandwich a piece of that between two pieces of plastic and bend that into a domed shape curved the proper amount for the frequency you are using and get the same or better results than any of the mod kits. Personally, I don't bother with the parabolic reflector antenna mods, because I am lazy and don't want to be bothered pointing the r/c at the aircraft all the time. So I use a bi directional signal amplifier that is made for the 5.8ghz control signal on my Standard. It gets range that is much farther than my battery will last if I were to not be careful.
Hope this helps.
