[600MRG] The best way to transfer power from TX to loading coil

[Andy - KU4XR]

Hi all:

I back, with a question now on the best way to transfer power from the transmitter into the loading coil..
I see several posts referring to auto-transformers, tappable torroid step-up / step-down transformers, etc.
I have a single coil, doing both jobs; TX Matching, And, Antenna Tuning .. Below is a dropbox link to a
picture of my Matching / Loading coil setup - to see what I am working with :

The picture shows the bottom is grounded, and I tap - UP - from the bottom to match the TX for 50 ohms..
Is there a Better / More Efficient way to transfer the power from the TX to the Coil ? Or, is what I am doing
perfectly acceptable ? Any mismatch that I have is due to Unknown Reactance in the antenna that I am
unable to measure, and wash out at the moment..

Thanks for comments, and suggestions, and 73 to all:
