HamAntCal+ 1.5.5

HamAntCalplus Version 1.5.5 (Ham Antenna Calculator Plus) provides a straightforward solution for determining the initial antenna length in feet/inches or metric units efficiently and intuitively.

The application offers calculations for various antenna types such as "Dipole," "Inverted Vee," "Vertical," and includes a dedicated page for lengths like 1/8, 1/4, 1/2, 5/8, and "Full Wave."

HamAntCalplus is optimized for usability on both iPad and iPhone devices.

This recent update includes:

• Optimization for iPhone X.
• Enhanced "Inverted Vee" functionality with a height slider for the ends above the ground.
• Compatibility with iOS 8.2 and newer versions.

Key Features:

• Calculations in feet/inches, decimal feet, inches under 10 feet, or metric units.
• Swipe left to access up to six saved antenna calculations per type.
• Estimate antenna length in free space.
• Determine a frequency between two input frequencies within a band.
• Adjust antenna element lengths based on diameter up to 1" using a diameter slider.

The application addresses discrepancies in determining the length of an "Inverted Vee" antenna through meticulous testing and calibration, offering users precise calculations. It encompasses a slider feature to adjust angles continuously, reflecting real-world performance accurately.

Note that precise measurements may vary depending on several factors, including wire material, height above ground, and surroundings. Thus, it's advisable to provide extra wire length for adjustments post-installation using an antenna analyzer or SWR meter.

The calculator covers frequency ranges from 30 kHz to 500 MHz for most calculations and up to 60 MHz for the "Inverted Vee" component. Users are reminded of potential influencing factors on resonant frequencies at VHF and higher bands, emphasizing the importance of fine-tuning antennas post-construction.

It is essential to prioritize safety precautions during antenna construction. Adherence to safety protocols and awareness of potential hazards, like power lines, is strongly advised throughout the installation process.

While the application offers reliable assistance in antenna design, users are encouraged to refine measurements based on practical testing and adjustments. Feedback and suggestions for enhancing HamAntCalplus are welcomed to continually improve user experience and accuracy in antenna construction.
