This antenna also designated as Marconi  'T' Antenna.

My vertical part is 17m running to the top of my Versatower.

The two horizontal parts are 28m.

Tuned ist this antenna  with  a simple LC-network.

How all  verticals this antenna need a good radial ground system.

I have about 80 radials each length from 5m to 40m, where I had place on my property.

Over years I experimented with TX antennas for 160m.

I had a V160HD,  INV  L antenna,  shunt fed tower,

and for my experience the  "T" is the best antenna I ever used.

The advantage of this antenna is, that the two horizontal parts works as topload.

Since I have this antenna,  I am mostly  No. 1 on pileups  on 160m.
