The anion gap **calculator** requires the serum sodium, chloride and bicarbonate to determine the anion gap, **delta** gap and **delta** ratio. These indicators offer information about the difference between primary measured cations and anions in serum and can help clinicians establish diagnosis of metabolic acidosis. Corned Fed **Delta Loop** - Author found a ratio between the lengths of the sides of the **Delta Loop** that give reasonably low SWR into a 50 ohm coaxial cable almost independent of the high above ground and other surroundings. This ratio also gives good results no matter orientation. Includes an online **delta loop** antenna **calculator**.. In the following, the construction of a simple multiband **delta-loop** antenna for the bands 80-10m is described. With the antenna calculation program EZNEC, the setup is theoretically prepared and documented with the inexpensive antenna analyzer miniVNA or graphically documented. Likewise, the advantages of a coaxial cable compared to a chicken. July 19, 2014September 17, 2014 Vertical **Delta Loops** 99 The Vertical **Delta Loop** • A three sided **loop** is known as a Vertical **Delta loop** sitting on the ground. • For best results, the lengths of the 3 sides should be approximately equal • The resistive impedance is ~130 interface with 4:1 BALUN • 2:1 VSWR Bandwidth Covers whole band at 40M and up (~ 4 % of Freq). Calculate BTU/hr. BTU/hr. = Gallons per hr x 8.33 x ?T°F. Calculate tons of cooling capacity. Tons = BTU/hr. ÷ 12,000. Oversize the chiller by 20%. Ideal Size in Tons = Tons x 1.2. If you follow these steps, you should have the ideal chiller size for your needs. The higher the temperature difference the higher the increase in length of the material (e.g. metal rod). The length difference ΔL is equal with the subtraction of the initial length L 0 from the final length L: By replacing (2) in (1), we can calculate the final length (after thermal expansion) function of the initial length, temperature. A 40-10 Meter sloping **Delta** **Loop** Antenna. Post #238. October 31, 2013. A one-wavelength **loop** is one of my favorite antennas. **Loops** may be built in a square, circular, rectangular, of triangular form to create an effective, inexpensive antenna. **Loops** can be built for single band service using coaxial cable and a quarter wave transformer or for. The 200 ohm **delta loop** has a wider SWR curve than the dipole, and the dimensions can easily be adjusted for the variation in **loop** impedance with height to give a nearly perfect match. The 50 ohm **delta loop** is only 5m across the top, compared to 10m for the dipole. This allows the antenna to fit between supports that don’t have room for a dipole. Karl, DK5EC, describes the construction of a simple multiband **delta** **loop** antenna (skywire) for the 80m - 10 m bands. The construction will be theoretically initialized with the help of the antenna calculation program EZNEC, and later measured and graphically documented with the inexpensive antenna analyzer miniVNA. MFJ MFJ-1788X - MFJ 1788 Super Hi-Q **Loop** Antennas. Antenna, Super Hi-Q **Loop**, Remote Tuning Type, Horizontal, Omni-directional Small **Loop**, 150 W, 15-40 m, 220 V. Part Number: MFJ-1788X. Not Yet Reviewed. Estimated Ship Date: Aug 9, 2022 (if ordered today). In side-by-side tests, my 80m **Delta** **loop** compares very favorably with my full-size 80m vertical which boasts 90 quarter-wave, or longer, radials. Broadside to the **Delta** **loop**, one gets ~ 4 dB of gain over the omnidirectional vertical, but one suffers the negative of this advantage in directions 90 degrees to the plane of the **delta** **loop**.. Understand how time accumulators work. Implement them. And apply actual time **delta** to physics and rendering, rather than some assumed constant dt. See if that serves you better. Because in the end, if the time **delta** is varying wildly on your given platform, there is nothing you can do about that but to simulate around it as described above.

Apr 14, 2002. 9,051. 1,361. 283. May 19, 2009. #1. I stumbled across this wire antenna project today. It's an interesting variation on a cross between a folded dipole and a **delta loop**. The original is posted at Dual **Loop** 80 and 40 Meter ZZ. It's a light magnetic **loop** antennacalculator that run on MS Windows, and allow to calculate capacitor values and voltage based on **Loop** circumference, conductor diameter, desired resonant frequency and the operating power. Works either in Standard and Metric units, and let you choose on material, and **loop** shape, as circular, square or octagon. Antenna efficiency: 83% (-0.8 dB below 100%) <- this is considerably better then 40m. Antenna bandwidth: 65.7 kHz <- No problem here, gives you 65khz space to move around before retuning the capacitor. Tuning Capacitance: 35 pF <- take note of this, as this is the low value for your variable cap.
