RAGE walkthrough part 4: Where's Juno and Radio Tower Repair

You get both these missions, Where's Juno and Radio Tower Repair, in the Outrigger camp while doing the Medical Supplies mission for Dan Hagar. Both missions lead you to the same area (Radio Tower) so it is advised to do the both simultaneously.

For Where's Juno, talk first to Rikter outrigger about the medical supplies that Dan Hagar needs. He will send you to Janus, who will give you this mission to find Juno:

You know the way it works here. We help you, you help us, right?
A member of our group, Juno, went missing a few days back.
Last I heard he was headed up to the Radio Tower to the Southwest.
Please look for him for me.
If you find any trace of him, I'll reward you with my Recipe for bandages.

Make sure to grab the collector card: Janus from the sofa nearby.

After you talk to Janus and get the quest, go back and talk to Rikter. He will ask you to go and repair the radio tower:

Couldn't help but notice stranger, that gun you're carrying isn't
much of anything. Help us out here, and I'll give you a real
weapon.
The Radio Tower to the Northeast stopped working, and we
need you to fix it. It was probably knocked out of alignment. So
just head up there and activate the Auto Calibrate.
You get it working again, and I'll give you a Combat Shotgun we uncovered.
Sound Good?

Make your way to the Radio Tower. You wont be able to drive the ATV there since it passes through a narrow trench, unpassable terrain for the vehicle, but its actually not so far away so you can just walk there. Make sure to watch out for and eliminate any bandits along the way.

The dotted lines will guide you which way to go. You will run into several bandits so be careful.

Eventually you reach the base of the Radio Tower. You will find Juno's corpse in a room there. There will be two dangerous mutants in that room so be prepared for a fight. Examine Juno's remains and the objective will change to inform Janus of Juno's fate.

Next, continue to the radio tower in order to activate the auto calibrator. Go down the hall and find the ladder leading to a rooftop. There will also be a Rikter Outrigger card nearby. After picking up the card Climb that ladder to the roof and throw the switch to auto calibrate the radio tower and complete the quest. Then head back to the Outrigger settlement through the Zipline (same as in the end of the Ghost Hideout area in Quell the Bandit Threat).

Talk to Rikter to get your reward, a Combat Shotgun. Then talk to Janus and inform her of Juno's fate. She will give you the supplies you needed for Dan Haggar, as well as some Rags, an antispetic formula, and a Bandage Recipe.
