Questions
Does Feedpoint need an internet connection?
No. It works fully offline and collects no data.
What is free and what is Pro?
Dipole, Inverted V and Vertical 1/4 are free. Pro adds cut sheets for end-fed half wave, J-pole, full-wave loop and quad, coax loss from manufacturer datasheets, cable lengths from velocity factor, grid locator with distance and bearing, and sharing a cut sheet. It is one purchase, no subscription, no ads.
Are the lengths exact?
They are starting lengths. Cut long, then trim with an antenna analyser. Height, ground and nearby objects move the resonance.
Which ITU regions are covered?
Region 1, 2 and 3, with a frequency lookup that finds your band.
