PhosphorCalc App Beschreibung und Prüfung

Was ist die phosphorcalc-app? RF and antenna calculator for amateur radio operators.
Ten standalone calculators on a clean, fast interface.
Numbers in, numbers out. No network, no accounts, no subscriptions.

DIPOLE
Calculate half-wave dipole, quarter-wave vertical, and full-wave loop antenna lengths for any frequency. Adjustable velocity factor for different wire types. Results in both metres and feet.

WAVELENGTH
Bidirectional frequency and wavelength conversion. Enter either value and the other is derived instantly. Identifies standard amateur band allocations (ITU Region 1) automatically.

PATH LOSS
Free space path loss calculator with approximate S-meter reading context. Supports kilometres and miles. Result can be imported directly into the Link Budget calculator.

COAX LOSS
Feedline attenuation for seven common cable types: RG-58, RG-8X, RG-213, LMR-240, LMR-400, Aircell 7, and Ecoflex 15. Uses log-linear interpolated manufacturer data across frequency. Shows power delivered to antenna from a 100W transmitter. Result can be imported into the ERP calculator.

ERP / EIRP
Effective radiated power accounting for transmitter output, feedline loss, and antenna gain. Supports both dBi and dBd gain input. Shows feed power, EIRP, and ERP in watts and dBW.

SWR
Standing wave ratio from forward and reflected power readings, or direct SWR entry. Calculates return loss, mismatch loss, reflection coefficient, and power delivered. Colour-coded SWR indicator: green for good, amber for marginal, red for poor.

POWER
Ohm's law solver: pick any two of voltage, current, resistance, and power — the other two are calculated. Separate dB conversion section converts between watts, milliwatts, dBm, and dBW.

LINK BUDGET
Complete end-to-end signal path analysis. Enter TX power, feedline losses, antenna gains, and path loss to see received signal power in dBm and microvolts, S-meter estimate, and link margin above noise floor. Selectable receiver bandwidth: CW, SSB, FM, or Digital.

LC RESONANCE
LC tank circuit calculator. Solve for resonant frequency, inductance, or capacitance given the other two values. Displays inductive and capacitive reactance at resonance as a cross-check.

IMPEDANCE
L-network impedance matching calculator. Given source and load impedance at a target frequency, calculates component values for both low-pass and high-pass matching network topologies. Shows Q factor and network orientation.

FEATURES
