All your problems will go away if you build some open wire line and

Those who believe this seem not to realize that any imbalance in the
antenna SYSTEM causes the feedline to carry common mode current both on
RX and TX. That may be no big deal on TX, but on RX, the common mode
current created by noise pickup couples to the antenna if the system is
less than perfectly balanced. As noted in an earlier post, most wire
antennas that we mere mortals can install are unbalanced by their
surroundings or by asymmetry in their construction or rigging.
