Hola Juan Luis.

Yo la suelo controlar de modo remoto, enviáme un msg privado a mi correo y te intentaré ayudar.
Un saludo

Hola,

Hablando de StepIr de 4 elementos.
Ayer escuché que un colega había derretido una de esas metiéndole 10 Kw...
No se hasta que punto es cierto pero encontré el colega y efectivamente tiene un ampli de 10 Kw procedente de un submarino ruso.

El colega es el Sultán Al Qasimi - A61AQ;

Hola Campeones:
La antena del video creo que es un Munstir que
tambien lleva 4 elementos, existe una de cuatro que sin el kit
de 30/40m llega solo hasta 20m.
El amplificador creo que se fabrica actualmente
en Rusia para el ejercito y temas comerciales.
Segun mis informaciones la cinta de cobre con
amplificadores muy gordos se suele picar un poco, pero co los
del mercado de radioaficionados no pasa nada.
Lo interesante del video es el rotor gigante
que es necesario para estas antenas que rompen un Yaesu 2800
en un solo dia de vientos fuertes, hablo de los tornillos que
sujetan el rotor a la base y yo los tenia de un material for-
tisimo.
Yo supongo que el rotor es Ruso, me intentare enterar
si es comercial o por encargo, pues con la pasta del dueño se
puede uno imaginar cualquier cosa.
Juan Luis dame una llamada y comentamos lo que quieras.

Manolo, el rotor efectivamente es ruso. De hecho, siempre que veo cualquier estación rusa, siempre tienen ese tipo de rotor, en distintos tamaños, claro.

Me gustaría saber la marca, pero nunca lo he podido averiguar, asi que si te enteras... esperamos la información atentamente.

Hola a todos.
Pues si la información que tengo no es errónea se trata de un rotor militar llamado P-10.
(en ruso П-10).
73 y nos escuchamos en el IARU.

Hola,

Yo había visto el modelo escrito en cirilico pero no sabía que era una P, más parecía una N o una R.
Entonces ya sabemos que es ruso, militar y por lo menos conozco dos referencias, el P-10 y el P-12.

A ver si alguien se entera de algo más; donde los compran, precios, características, etc.

Hola,

Bueno, pues ya encontré la información.

I hope that article will help you understand the types of gear, and proper names of the stations where they were used. Photos of some of the gear is in the photo site.
Characteristics of antennas "large" or "average" are conventionally given the 30 years of experience operating on RK3MWD.

P-3 "Pechera" radar VHF released in 1948, has a gearbox housing of rectangular shape, mounted on a separately-standing tower of duralumin tubes.
Dannyeh on motor and synchro no.

P-8 "Volga" radar range of CF was produced from 1951 RPM antenna 2 / min. Gearbox mounted on the mast of a thick-walled duralumin tube diametrom120 mm. Apparently the prototype P-10 gear.
Dannyeh on motor and synchro no.

P-10 "Volga-A" radar range of CF was produced from 1953 gearbox with two HF current collectors, the maximum speed of rotation of the antenna 4 / min. DC motor SL-569 (power of 160 watts.) Or motor-generator HSC-1500 (power of 1000W.) Selsyns DB-404A - 3 units. Traverse gearbox under 80 mm in diameter., Attached to the mast through the flange with four bolts M10. In the first release gear mounted on the mast of the pipe later in the semi-telescopic mast Unzha (insert section 300 to 300 mm, height 1140 mm.), Which stood on the chassis behind the cab.
Reducer to rotate the "average" antenna, rotating the "big" antenna cuts off on the output shaft splines.

P-12, P-12M, P-12mA, P-12MP "Yenisei", "Sura" radar range of CF was produced from 1961 gearbox with two HF current collector that looks like a P-10 but larger in diameter and height. The maximum speed of the antenna 6 rev / min. there is a mechanical switch to lower the rate of two times. DC motor MI-22F (power of 370 watts.), DB-501A selsyns - 2 pcs. Traverse gearbox under 110 mm in diameter. attached to a folding mast with the four fingers can be mounted on a mast Unzha-1. When placing the station on the chassis of the car in the name of the station P-12M added the letter A, when placed in a separate trailer, the letter P.

P-18 "Terek" radar range comes with a CF 1972 Contemporary station to replace the P-12NP the antenna system further by size. Traverse gearbox under 110 mm in diameter. with two RF current collectors a bit like a P-12NP, but even more in size and therefore heavier.
Heavy, powerful gear well for a very "big" antennas.

P-121 P-122 P-121M, P-122 m "boat" RTS range VHF produced in 60 - 70 g. Reduction station troposphere communication designed for accurate positioning system of log-periodic antennas, antenna rotation speed 0.3 rev / min ., rf current collectors, but there are limit switches.

Mounting the antenna to the flange diameter of 100 mm. on radar gear on the earth based on three legs.
Compact gearbox is well suited for the rotation of the "average" antennas to be installed on the mast needed to be improved.

Ahora falta saber donde los vende y a que precio.

Hola,

Bueno, pues si alguien quiere uno de esos rotores militares super robustos, ya se como conseguirlos.
El amigo Alex UR4LL nos lo consigue.
El precio depende del modelo, estado y demás, pero me ha comentado que sería a partir de unos 350 € aproximadamente.
Lo malo, el transporte. Esos rotores son muy robustos y eso implica peso, y el peso en el transporte se paga. Sería cosa de buscar un transportista barato, aunque fuera por carretera, tren o como sea.

Por lo demás no habría problema de conseguirlos.

A ver quién se anima a traer el primero.

73, Máximo - EA1DDO

Muy bien por las gestiones Max, seguro que a má de un colega le viene bien el asunto...

Como tu dices lo que peor veo es el tema de transporte, pero todo es ponerse a ello como has echo tu...

Me quedo con la info.
