Would you install an ADF receiver for that reason? Personally I wouldn't.I would go always with a device that adds another level of safety.
Panel real estate and payload are rare commodities in most GA aircraft. I personally decided to get rid of ADF and DME during my panel upgrade in exchange of other layers of safety like a back-up battery system and a second navigator.Would you install an ADF receiver for that reason?

I was really just wondering what additional level of safety you see with marker beacons. My question assumes the available panel real estate and acceptable W&B.Panel real estate and payload are rare commodities in most GA aircraft.

I don't even think GPS has much to do with it. They took out the middle marker nav penalties back before I got my instrument rating (and that was in the cusp of IFR GPSs existing). Outer markers were never really required for anything, and inner markers were only found at the bigger airports.I have a 450 w/marker and have not heard it for years. FAA has taken most markers out since GPS became integrated into ATC system.
It is when you need 2 hours of avgas.Given that the price delta is a tenth of an AMU or two, I'd say the presence of an antenna would be the deciding factor. An hour and a half of avgas is not worth sweating.
