The floating coax shield but you will introduce another potential source of.
End fed antenna in attic.
Mfj 1984hp end fed 1 2 wave 40 10m 800w wire antenna end fed horizontal wire antennas or efhws cover multiple bands without traps stubs or resonators.
The infamous attic dipole.
Remote rf switch control box in the shack chooses which antenna is operational in the attic.
This was installed at a previous qth i will be the first or millionth remember i m from fl to affirm that the antenna is the determining factor for success when it comes to one s station set up.
Attic antennas many types of antenna can be mounted in the attic if you don t have radiant barrier.
Higher is better slingshot or bow and arrow to get wire up in the tree.
The better your antenna the more success you will have making contacts.
That would make your end fed antenna 150 feet long which is not a problem in itself.
Another stopgap measure would be to replace the coax with a length of insulated copper wire connected to the hi z terminal on the back panel of the frg 8800.
Mac af4ps fp 51 note.
The radiator is 45 feet of genuine 14 black polyethylene coated flex weave wire.
Mfj 1984hp come with 66 feet of wire and cover 40 30 20 15 and 10 meters.
The par electronics ef swl is an end fed short wave antenna optimally designed for 1 30 mhz reception.
End fed wires resonate on their 1 2 wave fundamental frequency plus all odd and even harmonics above.
You would eliminate a source of unwanted interference.
Single band antenna when fed by coax.
