I have used an L for many years. The issue about performance is really a
question of "does it matter?" Any antenna that deviates from a true 1/4wL
vertical (or higher) with a substantial ground system is a compromise design.
It looks like you have 59 feet available to you, not 130 feet. The extra 71
feet would require rather heroic effort and expense, whereas the added L wire
can be attached in a couple of hours of mechanical prep and related tuning.
The L design is used by many DXpeditions and a substantial number of home
stations. Why? Because they work fairly well compared to alternatives. If it
works in your situation, aim the pattern, which has a beamwidth > 180 degrees,
in the general direction of the population center of interest and don't look
back.
Good luck, and see you on Topband!
