High wind and rain prevent making antennas for 80 and 160m. Propagation: 10-12 meters - phenomenal, 15m - super, 20-17m - worse than above. 20m FT8 issue with laptop charger making noise and prevented ...

Signal propagation in the ionosphere ... the need for a high-frequency (HF) mission payload with a wide range of frequencies and low noise. Designing its antenna will be difficult, however ...

This is achieved by the use of high-power EM waves in several frequency bands (e.g., HF, VHF, and UHF). When considering military vehicles, several antennas are present in close proximity to the crew ...

In this paper, we show how the combination of 2D metastructures with conventional antennas and reflectors enables an unprecedented electromagnetic behavior, which is at the basis of new properties, ...

Wildfire smoke from Canada and the Western United States stretched across the continent this week, covering skies in a thick haze and triggering health alerts from Toronto to Philadelphia.

But homebrewing is far from a dead art, and as we’ll see in this installment of “The $50 Ham”, a WSPR beacon for the HF bands is actually ... how the Weak Signal Propagation Mode, or WSPR ...
