I found this link that describes an alternative approach for matching the transmitter to an end fed half wave antenna. Since it was used for the IHAB-2 20 meter balloon beacon I think I am on the right track. It uses a transformer wound on a FT-114-43 toroid. This will get rid of the Par matchbox, coax, right angle connector and so forth. That will be lighter and will fit in the body tube. So I'll send off for the toroid. Much better!
