You cannot get past the guard at the Kanto radio tower. He is there permanently for the entire game, no matter how much of the game you manage to defeat.
There is no way for you to get past the Guard that's blocking the staircase in the Radio Tower in Lavender Town in "Pokémon SoulSilver."
You cannot get past the cop at the Lavender Town radio tower. The guard is always going to be standing in front of the elevator. The cop tells you that the increase in criminal activity in radio towers prompted him to guard the elevator.
You don't there is nothing beyond the guard.
I think you're talking about the radio tower in Goldenrod City. You have to go to the underground tunnel in Goldenrod and talk to the Team Rocket person. They'll give you a team rocket uniform then you can get past the guard.
Go back to Lavender town and go in the radio station. The man standing looking at the wall will give you a radio upgrade.
Look around the place where the hair salons are. There should be a Rocket Uniform down there.
You get the seventh gym badge, come back defeat all the team rocket guys and he will let you up.
In Goldenrod City, there is no cop guarding the radio tower. In Lavender Town, it is impossible to get past the cop. You do not even need to get past that cop.
In order to bypass the guard, you must defeat Team Rocket and rescue the Director. You will be able to fight Team Rocket after you receive a phone call from Professor Oak, saying that there are weird transmissions coming from the tower.
you have to get passed a guard? werid! i didnt i just walked in but there was a rocket grunt standing near it.
You don't until you defeat the 7th Gym (Pryce - Ice Gym) you'll get a call about odd radio frequencies, when you try to put on the radio all you'll get is Team Rocket, which is hinting you to go to Goldenrod, where they are littered all around the city, to get rid of them you'll have to go underground and get the Team Rocket Uniform, then make your way past the Rocket Guard in the Radio Tower, defeat all of team rocket and the guard will be gone from there!
Once you get the 7th badge (or 8th, don't remember exactly) and come back through you can go higher in the tower to defeat team rocket.
