Richards,
.
1 - I currently have a 4-Bander Horizontal Wire Antenna
using a TV type 300 Ohm to 75 Ohm Matching Transformer
and 75 Ohm RG6 Coax Cable feed-in-line.
.
2 - It can also be Rigged as a Sloper with a Couterpose
* Just 25 Foot Long
* Rig the Apex at 20 Feet with the Far-End at 8 Feet
* Use a 20 Foot Counterpose
* 22 Feet of Ground Space {Foot-Print} at 60 Degree Angle
* 18 Feet of Ground Space {Foot-Print} at 45 Degree Angle
.
3- For very "Limited' Space rig it as a Vertical
* Bottom Feed-Point at/near Ground Level
* Use a Ground Rod at the Base -if- possible
* Apex High-End-Point 25-26 Feet
.

= 50 Feet ~ 1/4 WL for 60M Shortwave Band ~ 5.0 MHz
= 37.5 Feet ~ 1/4 WL for 49M Shortwave Band ~ 6.1 MHz
= 25 Feet ~ 1/4 WL for 31M Shortwave Band ~ 9.6 MHz
= 12.5 Feet ~ 1/4 WL for 16M Shortwave Band ~ 17.8 MHz

"X" = Antenna Feed-Point Connection
"o" = End 'No' Connection
"|" = Wire-to-Wire Connection
