Rotor interface

PST-641 / Fireco InterfaceLast year I purchased a pneumatic 11m mast that can support a head load of 35kg.  Currently I use an SPID RAU rotator from AlfaRadio mounted at the top of the mast to rotate antenna’s.  At 6kg the rotor is reasonably light but for a while I’ve felt it would be better placed at the base as this removes 6kg from the top of the mast.

This little project will need modifications to the masts support/tilt-over base, a new rotor – as the SPID won’t take the vertical load – and an interface between the rotor and mast.

PST-641 / Fireco InterfaceThe project has taken the first step.  After drafting an engineering drawing of the rotor/mast interface a local engineering company made one for me.  For reference the rotor is a Prosistel PST-641D and the mast is a Total Mast Solutions / Fireco 115mm (base tube) pneumatic mast.

I’ll post again next month when I hope to receive the new PST-641D rotor and progress the next stage in the project.

Pneumatic Masts

As some of you will know I’ve been looking at getting a mast for my home which could, if necessary, be removed and used for portable operations.  Some of you will also know that I’ve settled upon a pneumatic mast from Total Mast Solutions (TMS) here in the UK.

The TMS website is not great; the range of masts is huge and information that details the range and available options is either hard to find or non-existent.  After much digging this morning I’ve come to understand that TMS are the UK reseller of masts made by an Italian company – Fireco.  That company has partners worldwide but again its hard to find good informaiton.  However, the Australian partner (EVTA Group) does have a website that provides lots of detailed information and I strongly recommend anyone considering one of the masts to download the Full catalogue, understand the range and options, then download the brouchure specific to the mast range of interest before calling/emailing TMS.

The links I provide here will age, so for up to date information I recommend you always go direct to the TMS and/or EVTA Group Australia website.
