Antenna+ vs Map

Your care and curiosity make every radio project better. Thank you for using Antenna+. From your first dipole to your next Morse practice session, keep useful antenna calculators, RF tools and saved results close on iPhone, iPad and Apple Watch. PLAN YOUR ANTENNA - Size a 5/8 wave vertical for your operating frequency. - Find half-wave dipole lengths and the length of each leg. - Compare dipole and inverted vee dimensions. - Work out ground plane radiators and radials. - Calculate cubical quad loops, double bazooka antennas and extended Zepp dimensions. - Convert frequency to full and fractional wavelengths. - Choose metric or imperial length units. - Read the formulas and assumptions in Help. CHECK YOUR RF NUMBERS - Convert watts, milliwatts, dBW and dBm. - Calculate ERP and EIRP from power and antenna gain. - Include feed line and connector loss in EIRP estimates. - Explore VSWR, mismatch loss and reflected power. - Estimate geometric and radio horizon distances. - Look up sunrise, sunset, solar noon and twilight for a chosen place, date and time zone. - Save the inputs alongside each calculated result. PRACTICE MORSE AND TONES - Turn text into Morse code and audible practice tones. - Use a straight key or enter individual dots and dashes. - Adjust Morse speed and sidetone settings. - Decode Morse and DTMF audio through the microphone. - Microphone listening starts only when you choose Receive or Start Listening. - Play standard DTMF keypad tones and sequences. - Exchange acoustic text with nearby devices using their speakers and microphones. - Replay the latest sent chat message from its bubble. - Stop a transmission when you need to cancel. - Search Q codes and add them to a message draft. KEEP YOUR WORK ORGANIZED - Give saved calculations and signal records a title and notes. - Mark favorites, filter by date and search by tool or content. - Review original inputs and results without recalculating. - Read all your saved results without spending another use. - Scroll through your records with automatic loading. - Explore charts and summaries of your saved calculations. - Back up and restore records with JSON import and export. - Skip matching records during import. - Export records to CSV for a spreadsheet. - Process up to 10,000 records per transfer, with a 100 MB JSON archive limit. TAKE IT TO APPLE WATCH - Use all 14 calculators without a usage limit or Pro purchase. - Calculate on your watch without the iPhone app or a phone connection. - Keep the watch screen clear with short text labels. - Find Save, Share and Help at the bottom of calculator pages. - Save calculations locally on your watch and reopen them in Saved. - Share full calculation details using the watch's available sharing options. - Practice Morse with Key, Dot, Dash, Play and Stop. - Get haptic feedback and sound when audio is available. - Keep watch records separate from the records on your phone. FIND WHAT YOU NEED - Keep favorite chats, signal tools and calculators within easy reach. - Use the iPad's list and detail layout to browse while viewing a tool. - Open ham radio and antenna references in the app's browser. - Bookmark useful web pages for another visit. - Choose System, Light or Dark appearance on iPhone and iPad. - Restore your previous Pro purchases from inside the app. Use calculated antenna dimensions as a starting point, then tune for your installation. Acoustic chat uses sound between nearby devices. iPhone and iPad include a one-time allowance of 50 uses per device. Continue with monthly or annual auto-renewing Pro, or a one-time Lifetime Pro purchase. Apple Watch calculators and Morse remain unlimited without Pro. Web references require an internet connection. For monthly subscriptions: Monthly Pro is a 1-month auto-renewable subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Map-n-Compass is a specialized app designed for those interested in Orienteering and Amateur Radio Direction Finding navigation sports. The app is designed specifically for individuals and groups interested in learning and practicing these outdoor navigation sports. If these navigation sports are not your passion, then this app may not be for you. PLEASE NOTE: Continued use of GPS running in the background can dramatically decrease battery life. This app is about getting outside, designing courses, and navigation: Map-n-Compass is designed to help beginners develop the skills needed for Orienteering and Amateur Radio Direction Finding navigation sports. The beginner skill level lets newcomers learn without frustration. Intermediate and advanced skill levels provided progressively more challenge. For event organizers the app provides support for designing and distributing courses and holding informal practice sessions with minimal cost and effort. Please contact Digital Confections to provide suggestions for enhancing the app! FEATURES Groups with multiple iOS devices running the app can hold informal practice sessions with minimal cost and effort. The map, the compass, courses, controls, and results recording are all supported within the app. Assorted "streamed" street maps are available within the app, or custom maps can be downloaded and displayed within the app, and a small sample map is provided for illustration. o Help is available within the app - just swipe up on any available overlay or button to access specific help. o Universal - the app is fully functional on iPhones and iPads with GPS. o The app works even on "deactivated" devices lacking cellular network coverage. (Streamed maps and email will not be available without network coverage.) o GPS data is digitally filtered to enhance position accuracy. o Results files contain track, overall results and splits. o Course and Results file sharing by email or iTunes file sharing. o KML-format course and results files are compatible with free mapping software available from popular vendors. o Custom map tile databases that you create and install are supported. o Digital compass data provides directional information. o Tiered support for beginner, intermediate and advanced skill levels. o Multiple options for automatically rotating the map. o Built-in timers: Time of day clock, Elapsed time, Overtime countdown with alarm. o Text data can be overlaid atop the map: Distance, step count, GPS, and much more. o Speed and distance unit selection, time format, lat/lon format changes are applied instantly with a single swipe. o Leg lengths and GPS locations of control points can be displayed for courses you create or download. o Courses can be created on a PC or Mac running freely-available satellite photo software, then exported and downloaded to the app by email or iTunes file sharing. o Courses can be created within the app and then shared by email with others using the app, or tweaked on a PC or Mac. o Results files can be displayed and "animated" in free Earth satellite-view software to "relive" the experience - and combined with the results of others to see locations over time. ORIENTEERING o Beginners can see their location on the map, and receive distance and direction hints o Intermediate level users get fewer hints. o Advanced level users get no help from the app aside from a convenient paperless map, map rotation support and course display. ARDF o Bearings are recorded in "point and shoot" fashion, and are color coded to their intended target. o From one up to five separate "foxes" can be hunted and tracked. o Transmitter signals are simulated to provide a remarkably realistic simulated transmitter hunt experience. o Can be used for bearing recording to live transmitters. o The app calculates and displays the likely target locations based on bearings taken. o Results files include bearings and target calculations.
