Default HF antenna assistance

Hi folks

Although licensed for over 12 years as a G7... converting 3 years ago to a
M0...callsign (with 12 wpm cw), personal circumstances have not until now
permitted me to get started on HF.

Problem now is antennas (and indirectly xyl).

Have garden to rear of property, narrow but 80' long from house to boundary.
A further 25' is available along side of property, rear to front, but
approx 6' proximity to house wall.
Height of proposed feedpoint approx 17' 6" ; height at boundary 12'

Would initially like to cover 14 - 7 and 3.5 MHz with a coax fed
horizontal wire dipole of approx 66', and if carefully cut would
theoretically get full - 1/2 and 1/4 wave respectively for these bands. An
MFJ-949E Atu is available. No garden or roof space for any vertical metal!

That's the idea, but I would welcome constructive comment, especially in the
area of feedpoint impedances and swr.

My thanks in anticipation. . . .
Jim

Carolina Windom for 40m to 10m, trapped dipole (yuck!) for 80m.
