End‑Fed & Long‑Wire HF Antennas

 

Terminated End Fed Vee Antenna (TEFV)

The TEFV is a terminated end‑fed Vee antenna intended for broadband HF coverage with minimal retuning. By accepting some efficiency loss in exchange for wide bandwidth and a quieter noise floor, it becomes a strong choice for multi‑band HF monitoring and casual operating. The article covers geometry, termination values, matching network and practical test results.

Multiband Half Wave End Fed Antenna
This multiband EFHW antenna uses a 1:49 transformer and carefully chosen wire length to cover several HF bands from a single feed point. It targets small‑plot or portable QRP operators who want 80 through 10 metre coverage with minimal hardware. Construction details, winding instructions and on‑air performance observations are provided for easy replication.

Building End Fed Half Wave Antenna (EFHW) for 40M – 10M
A practical EFHW focused on 40 to 10 metres gives solid multiband capabilities with a simple transformer and single wire. This project walks through transformer design, wire‑length tables, support options and tuning in real‑world conditions. It is aimed at portable, balcony and field operators who need quick deployment and predictable tuner behaviour.

Tree Mounted Quarter-Wave Vertical Antenna
The tree‑mounted quarter‑wave vertical shows how to hide an efficient HF radiator in plain sight by strapping it to an existing tree. Radials or counterpoise wires complete the system, giving low‑angle radiation for DX while remaining visually stealthy. The article explains mechanical fastening, wire routing, matching and on‑air performance from a typical suburban lot.

Antenna – Folded Beverage Antenna for HF Bands
This folded Beverage antenna is a receive‑only design built for serious HF DX listening with excellent noise rejection. It uses a long, low wire with specific folding and termination to achieve directional gain at low angles. The guide explains impedance, matching a 450‑ohm line to coax, termination design and how to protect the load from accidental RF power.
