RF Engineer Toolkit is the calculator set RF engineers, tower and DAS technicians, PCB designers, and radio amateurs reach for every day. 45 calculators, every formula unit-tested against Pozar, Balanis, ICNIRP 2020, FCC OET-65, and manufacturer cable data — with live results, locale-aware input, and no ads. FIELD AND SITE • VSWR, return loss, reflection coefficient, and mismatch loss from any one value or a wattmeter reading. • Cable loss with manufacturer coefficients (LMR, RG, Heliax, 9913), SWR loss, and ERP. • Link budget with FSPL, cable losses, gains, sensitivity, and margin. • Antenna downtilt and coverage, radio horizon, Fresnel zone with earth bulge and clearance. • RF exposure against FCC and ICNIRP limits, with safe distance for public and occupational exposure. • Antenna separation and co-site isolation, including required spacing. • Dipole, helical, and parabolic dish design, near-field boundaries, and Doppler shift. DESIGN AND LAB • Smith chart with series and shunt elements, lines and stubs, exportable as an image. • Impedance matching networks (L, Pi, T) with Q and bandwidth. • Attenuators (Pi, Tee, bridged-T, L-pad) with E24 and E96 values and real achieved attenuation. • LC filter designer: Butterworth and Chebyshev, low-pass, high-pass, band-pass, and band-stop. • Receiver chain: cascaded gain, noise figure, IP3, noise floor, and SFDR. • Amplifier linearity: P1dB, IP3, back-off, IM3, and PAE. • Microstrip, stripline, coplanar, and differential-pair impedance with synthesis and substrate presets. • Coax impedance, cable delay and phase, quarter-wave transformers, and skin depth. • Power dividers and directional couplers, S-parameter conversion, and intermodulation products. • Rectangular and circular waveguides with WR tables, cutoff, and guide wavelength. EVERYDAY CALCULATORS • dBm, dBW, W, V, dBV, dBµV, dBu, and dBi/dBd conversion. • Wavelength, reactance, resonance, time constants, Ohm's law, dividers, series and parallel circuits.

Designing dipole antennas just got easier. Whether you’re a ham radio enthusiast, RF engineer, or hobbyist, this app helps you compute the essential dimensions and performance parameters for various dipole antenna configurations — and it even factors in wire diameter, which is especially critical at UHF frequencies. Key Features - Accurate length & parameter calculations — Generate precise values for half-wave, full-wave, folded, and other dipole types - Wire diameter effect included — Adjustments for conductor diameter yield more realistic results, especially at UHF - Support for multiple dipole designs — Choose among standard configurations and tailor to your needs - Clear, intuitive interface — Easy input of frequency, wire gauge, materials, and more - Instant updates — See how changes to any variable affect the resulting dimensions - Continuous improvements & fixes — Updated for stability and accuracy Why It Matters? At UHF frequencies, ignoring the effect of wire diameter can lead to significant discrepancies in antenna performance. This app bridges that gap, helping you design antennas that closely match real-world results. Who Can Benefit - Amateur radio (ham) operators - RF engineers & students - Antenna hobbyists and experimenters Anyone needing quick, reliable dipole calculations on the go In app purchase included : Lifetime Premium Privacy policy : https://privacypolicy50.wordpress.com/privacy-policy-subscription/ Terms and condition :https://privacypolicy50.wordpress.com/terms-and-condition/

Verdict
The clearest difference is rating: RF Engineer Toolkit at 5.0 against Dipole calculator's 4.3. Dipole calculator's advantage is ratings volume (7 vs 1) and iOS requirement (13.0 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. RF Engineer Toolkit sells 3 in-app purchases, starting at $0.99 per month and Dipole calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
RF Engineer Toolkit holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Dipole calculator has 7 ratings behind it against 1, so its average is the more settled of the two.
