De la Cierva developed his model with the assistance of Spain's Military Aviation establishment, having expended all his funds on development and construction of the first five prototypes. The first flew in February 1925, piloted by Captain Joaquín Loriga , [11] including a flight of  km ( mi) from Cuatro Vientos airfield to Getafe airfield in about 8 minutes, a significant accomplishment for any rotorcraft of the time. Shortly after De la Cierva's success with the , Cierva accepted an offer from Scottish industrialist James G. Weir to establish the Cierva Autogiro Company in England, following a demonstration of the before the British Air Ministry at RAE Farnborough , on 20 October 1925. Britain had become the world centre of autogyro development.

b) Dispense with the vertical and instead mount a random, horizontal dipole with the ATU and feedpoint above the pilothouse. The front half of the dipole would be mounted between the ATU and a forward mast at the bow. Not sure of how the stern facing emlement would be mounted and consideration would have to be made regarding davit usage. Dipoles don’t rely on a ground, they are a balanced antenna with both halves working together. You can have an off-set dipole, that would work fine. For instance, a total of 50 feet of off-set dipole could be constructed with a single leg of 35 feet towards the front and another leg of maybe only 15 feet going backwards. Radio Amateurs might call this an off-set Doublet.
