It will calculate the starting length for "Dipole's", "Inverted Vee's", "Vertical's" and has a page for calculating 1/8, 1/4, 1/2, 5/8 and "Full Wave" length. In this update: ▪HamAntCal has been updated to 64 bit and iPhone X ▪New updated interface and settings menu ▪New in app purchase to update features ▪This update requires iOS 8.2 and above. --------------------------------------- ▪ HamAntCal works in feet/inches as well as metric. ▪ The easy to use and intuitive interface makes it easy to calculate starting lengths for building your antennas. It will calculate the starting length for "Dipoles", "Verticals" and "Inverted Vee" antennas. There is also a page for calculating 1/8, 1/4, 1/2, 5/8 and "Full Wave" length. ▪ I have come across a lot of different and conflicting information for calculating the length of an "Inverted Vee" antenna. Some say subtract 2 to 5 percent based on the angle of the wires. Others say to add a percentage based on the angle of the wires down from horizontal. I decided to test this before releasing this app. First I calculated for a "Dipole" using the "Dipole" calculator. Then I put together a "Dipole" with a support for the center insulator as well as the ends. I measured the resonant frequency with an antenna analyzer. Then I brought the ends down towards 45 degrees from horizontal. As the ends were lowered the resonant frequency increased. This means that the length of the "Inverted Vee" would need to be increased to stay resonant at the same frequency as the dipole. The "Inverted Vee" calculator has a slider that starts up with an angle of 45 degrees and can be adjusted down to 20 degrees continuously re-calculating as it is moved. This corresponds to about 4.5 to 2 percent added to the length of the "Inverted Vee". ▪ No antenna calculator can give exact results in every case. Much will depend on the wire used, the height above ground, the ground itself, nearby objects, etc…. It's always a good practice to add a little extra wire and then trim up to the desired frequency. ▪ This calculator will calculate from 30 Khz to 500Mhz for the "Dipole", "Vertical" and "Length" calculators. The maximum for the "Inverted Vee" calculator is 60MHz. ▪ This calculator does not give exact measurements and the results will need to be trimmed using an antenna analyzer or SWR meter to the exact frequency after installation. Leave some extra wire on each section for trimming and wrapping around the insulators. ▪ Keep in mind that there are a lot of factors that can affect the resonant frequency of an antenna. At VHF and above even a small change in the length or diameter of an element can make a large change in the resonant frequency of an antenna even more so than at lower frequencies. This calculator just provides the starting length for building an antenna and proper matching methods will need to be used. ▪ Please be safe while building your antennas. Always use the proper safety equipment. Never build your antenna where it can come in contact with power lines, this includes the supports as well as the antenna itself and feed lines. BE SAFE! ▪ Although I have had good results using this calculator the results are not guaranteed. Always add some extra length and trim the antenna to frequency (it's much easier to trim than it is to add wire to the antenna).

I can do length calculations on my phones calculator. -- beltdtive, 2023-12-29 ### ****- "No longer works with IOS 11" This used to be a great app. But it has not been updated in awhile. This version will not work with IOS 11 until updated. This has since been updated, it is once again a great app. Thanks so much -- MmillerFL, 2017-12-24 ### ***** "Great tool for ham radio!" love this app and will continue to use it! -- Up north Jay, 2017-12-11 ### ***-- "Needs UHF & above" Please add support for UHF frequencies and higher. -- TheGadgetinator, 2017-12-11 ### ***** "Can you PLEASE update this Great APP?" I want to thank you so much for the Great FREE reference APP that i have used playing out in the field portable, and for quick calculations when pre-planning different dipoles on the go, and at the home QTH Antenna Farm!! I Really appreciated the use of this APP, can you please update it, because it win’t work on the iOS 11. Update😐thanks a lot apple🙁 Yes i was real dumb not to support it with buying the full version! I am sorry! Thank You for the Years of Great Use!! KG4JXH-Daniel -- Sportbike=fun, 2017-11-25 ### ***** "Update Please" This app was a 5, but is now a 1 since I can’t use it anymore. Please update it to work with the latest iPhone update! Thanks! -- Hsisdusnsjfbvs, 2017-10-15 ### ***** "K9JDP" Great app use it all the time 👍 -- Jporterfield, 2016-12-01 ### ***** "What do you expect" Love this app, comes close as stated, I have an antenna analyzer to finish it off, would recommend it to anyone, lots of fun in the middle of a thought, instead of pulling out an actual Calculator and going through all the math, gives me something to think about -- Short stroke, 2016-11-21 ### *---- "App is wrong on inverted V" This app calculates wrong on inverted V. Inverted V antennas are up to 5% shorter than a dipole. Don't trust this app. Needs to be corrected W9KJO -- Whiffing, 2016-10-09 ### ***** "I love it" Thanks JG for an awesome simple to use tool that will get ya in the ball park for basic Wire Dipole antenna building . This will come in handy for field day demonstrations and camping 😎 -- The burntmexican, 2016-09-22 ### ***** "Great program" Very easy to use. -- Xman4u, 2016-04-04 ### ***** "Great app" Suggestion. Let me put in a target frequency and a measured frequency and then show how much I need to trim or add. -- sysproger, 2015-09-20 ### ***** "2easy" So easy even a caveman could use it -- Yeah-haa, 2015-09-14 ### *---- "Useless & Very Rudimental" Any experienced antenna designer will find this app as useful as using a 12 inch ruler measuring 100 feet length. I am shocked with the reviews this app has gotten. It's ridiculous to even presume this numbers will even come close to the correct length of an actual design. Handful of factors could have been easily coded to its sub-routine. At least adding the velocity factor and size of radiating element as a variable field. This will drastically give ham operators a better chance of getting a more realistic and accurate result. -- Pet Natividad, 2015-07-19 ### ***** "W4KKP" My favorite part of the hobby is making antennas, so this app is used often. If more features were added this app would sell to hams and other DX chasers. -- Benhaven01, 2015-07-07 ### ***** "Another tool!!!!" Great addition to iphone 6+!! -- Outtaram, 2015-05-15 ### ***** "Great application" It does just what it is supposed to do in a quick, easily understood format. -- N7ELZ, 2015-04-24 ### ***-- "Nice but limited" It a nice app, but limited as it can not calculate high frequencies. Worth the money. -- KC0SHO, 2015-03-08 ### ***** "Great tool!" This is awesome and right at your finger tips. Sure you could open up your calculator and punch in the numbers but this gives you 1/4, 1/8, 5/8 lengths too plus other features. -- Greg 1979, 2015-01-07 ### ***** "Works great" Works great on my pos gen 4 ipod. -- ={ AlanE }=, 2015-01-06 [View all HamAntCal reviews and detailed analytics on AppTail](https://apptail.io/ru/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## HamAntCal In-App Purchases | Item | Price | |------|-------| | Features upgrade | $0.99 | ## HamAntCal Discovered Keywords - antenna calculator ## HamAntCal Available In - [Соединенные Штаты](https://apptail.io/ru/app/hamantcal-Ohmf/united-states) - [Канада](https://apptail.io/ru/app/hamantcal-Ohmf/canada) - [Австралия](https://apptail.io/ru/app/hamantcal-Ohmf/australia) - [Бразилия](https://apptail.io/ru/app/hamantcal-Ohmf/brazil) - [Малайзия](https://apptail.io/ru/app/hamantcal-Ohmf/malaysia) - [Новая Зеландия](https://apptail.io/ru/app/hamantcal-Ohmf/new-zealand) - [Таиланд](https://apptail.io/ru/app/hamantcal-Ohmf/thailand) - [Чили](https://apptail.io/ru/app/hamantcal-Ohmf/chile) - [Доминиканская Республика](https://apptail.io/ru/app/hamantcal-Ohmf/dominican-republic) - [Алжир](https://apptail.io/ru/app/hamantcal-Ohmf/algeria) - [Эквадор](https://apptail.io/ru/app/hamantcal-Ohmf/ecuador) - [Египет](https://apptail.io/ru/app/hamantcal-Ohmf/egypt) - [Гренада](https://apptail.io/ru/app/hamantcal-Ohmf/grenada) - [Гонконг (САР)](https://apptail.io/ru/app/hamantcal-Ohmf/hong-kong) - [Индонезия](https://apptail.io/ru/app/hamantcal-Ohmf/indonesia) - [Израиль](https://apptail.io/ru/app/hamantcal-Ohmf/israel) - [Индия](https://apptail.io/ru/app/hamantcal-Ohmf/india) - [Япония](https://apptail.io/ru/app/hamantcal-Ohmf/japan) - [Кения](https://apptail.io/ru/app/hamantcal-Ohmf/kenya) - [Республика Корея](https://apptail.io/ru/app/hamantcal-Ohmf/south-korea) - [Кувейт](https://apptail.io/ru/app/hamantcal-Ohmf/kuwait) - [о-ва Кайман](https://apptail.io/ru/app/hamantcal-Ohmf/cayman-islands) - [Казахстан](https://apptail.io/ru/app/hamantcal-Ohmf/kazakhstan) - [Ливан](https://apptail.io/ru/app/hamantcal-Ohmf/lebanon) - [Шри-Ланка](https://apptail.io/ru/app/hamantcal-Ohmf/sri-lanka) - [Мали](https://apptail.io/ru/app/hamantcal-Ohmf/mali) - [Мексика](https://apptail.io/ru/app/hamantcal-Ohmf/mexico) - [Намибия](https://apptail.io/ru/app/hamantcal-Ohmf/namibia) - [Нигерия](https://apptail.io/ru/app/hamantcal-Ohmf/nigeria) - [Непал](https://apptail.io/ru/app/hamantcal-Ohmf/nepal) - [Оман](https://apptail.io/ru/app/hamantcal-Ohmf/oman) - [Перу](https://apptail.io/ru/app/hamantcal-Ohmf/peru) - [Филиппины](https://apptail.io/ru/app/hamantcal-Ohmf/philippines) - [Пакистан](https://apptail.io/ru/app/hamantcal-Ohmf/pakistan) - [Саудовская Аравия](https://apptail.io/ru/app/hamantcal-Ohmf/saudi-arabia) - [Сингапур](https://apptail.io/ru/app/hamantcal-Ohmf/singapore) - [Тайвань](https://apptail.io/ru/app/hamantcal-Ohmf/taiwan) - [Уганда](https://apptail.io/ru/app/hamantcal-Ohmf/uganda) - [Вьетнам](https://apptail.io/ru/app/hamantcal-Ohmf/vietnam) - [ОАЭ](https://apptail.io/ru/app/hamantcal-Ohmf/united-arab-emirates) - [Южно-Африканская Республика](https://apptail.io/ru/app/hamantcal-Ohmf/south-africa) - [Армения](https://apptail.io/ru/app/hamantcal-Ohmf/armenia) - [Аргентина](https://apptail.io/ru/app/hamantcal-Ohmf/argentina) - [Азербайджан](https://apptail.io/ru/app/hamantcal-Ohmf/azerbaijan) - [Бермудские о-ва](https://apptail.io/ru/app/hamantcal-Ohmf/bermuda) - [Бруней](https://apptail.io/ru/app/hamantcal-Ohmf/brunei) - [Китай](https://apptail.io/ru/app/hamantcal-Ohmf/china) - [Колумбия](https://apptail.io/ru/app/hamantcal-Ohmf/colombia) --- ## About AppTail [AppTail](https://apptail.io/ru) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
