Living in a deed restricted community and the confines of those “no antenna” restrictions I still enjoy HF bands. Most of the time I operate on the 20M and 40M bands in CW and, digital modes using an attic dipole.
なるほどそれは難儀なことで。
だが、
I have found using a vertical full wavelength delta loop for portable operations is a nice improvement over my rather NVIS attic dipole.
The team installed two new antennas which will provide more gain on 12/17/30/40M than the previous antennas. The new antenna models are 11-5 @ 70' and Duo 30/40 @ 80' from GXP Poland.
EHZI Antenna 27 MHz for low-profile auto, the plane of the pendant is visible, consists of two screw resonant waveguides. Compact, reliable in operation, does not require tuning, competitor to the moraine de luxe antenna.
This antenna is promising for a range of 160 m, since it will have a diameter of 120 cm and a height of only 10-20 cm, depending on the thickness of the wire.
The antenna covers the entire euro grid and captures other, higher-frequency grids, low-frequency cuts. The principle of the antenna is electrodynamic induction.
At its core, the induction cavity - two antiphase resonators create tension around the antenna, the SS is also a resonator but emits a current.
