LVOT ACC (m/s 2) = Vmax (m/s)/ACT (s). When systolic function is normal, the LV ejection curve resembles a sharp-angled triangle. With impaired left ventricular function, the ejection curve becomes flattened and rounded, i.e., with a decreased peak velocity and an increased ACT.
The Hermes Loop RX Antenna at VK1HW. I've had a bit of Aluminium bar lying around and so I've build a Hermes Loop with a 1m diameter. I've build a few single loops before, but only.I have constructed a few 40 dB resistive Taps using a T resistive divider .

Learn about different types of loop antennas for ham radio use, such as small, full wave, large, and intermediate loops. Find practical projects and construction tips for loop .
Small, directly-fed loops are DC-shorted feedpoint antennas, with associated immunity to static buildup and lightning-induced energy pulses. The first point above is mostly .
Lowering the antenna is quite easy. I disconnected the 183Ω feed-line, opened the loop and attached 8.5m of 2.5mm insulated copper wire the loop. Up she went, and a 40 meter . I want to put up a magnetic loop antenna for the upcoming DX season and am trying to decide on a rigid loop antenna like the Wellbrook ALA1530LN or a Bonito MegaLoop FX . Learn about different types of loop antennas for ham radio use, such as small, full wave, large, and intermediate loops. Find practical projects and construction tips for loop antennas, including quads, delta loops, and arrays.
Learn how to build wire loop antennas for different bands and purposes, using stiff wire, strung wire, or hung loops. See photos and diagrams of various designs, such as quads, deltas, and hexagons. Learn how to build and tune a full wave loop antenna, a continuous loop of wire or other conductor approximately one wavelength long. Compare different loop shapes, feedpoint positions, and polarizations, and see the effects of ground and environment on the radiation patterns and impedance. Learn how to design and build wire quads, parasitic loop arrays for ham radio antennas. See examples of 2-element delta loops for 10m and 15m bands, with dimensions, SWR, and pattern plots.
Learn how the size, shape, and feedpoint location of loop antennas affect their radiation patterns and feedpoint impedances. See examples of square, circular, and rectangular loops in free space and over ground. 80m Horizontal Loop for Field Day. last updated 31 March 2023. This horizontal loop (or “sky loop”) was developed for use on Field Day, with a specific site and radiation pattern in mind. Your requirements may be different, but the .Learn how to build a bow-tie horizontal loop antenna that can operate on two HF bands with maximum radiation overhead for NVIS. See the dimensions, feedpoint impedance, and current distribution for this antenna design.
Portable 200 ohm Loop. This antenna often replaces our 40m half wave dipoles for Field Day. The gain and radiation angle aren’t quite as good as a dipole at the same top height (although there is less loss in the shorter coax), but it isn’t quite as wide. And the SWR bandwidth is much better: under 1.3 : 1 or so from 7.0 to 7.3 MHz.
Learn about double loops antennas, a form of broadside gain antenna with two loops in a single structure. Find out how to build and feed different shapes, such as double rectangles, double deltas, double diamonds, and single diamonds, and .
