Ropes and the sea salt - is it true, that in the marine air will collect sea salt in the rope braids and eventually will become conductive?
- That is correct - it is true that once the rope gets wet from salt water, it can start to become partially conductive, which can affect the electrical performance of antenna systems. This is an occasional problem with insulators, by the way. However, in the 14 years of Mastrant's existence, we have satisfied hundreds of customers with antennas right on the shoreline, and as far as I know, this temporary change in conductivity has never caused a loss of satisfaction or confidence in our ropes.
Are the BAYCO monofilament ropes better than your Mastrant ropes for guywiring a tower? It looks like the Bayco do not absorbe water.
Mastrant ropes are developed for anchoring masts, and the fibres from which they are made (Polyester, Dyneema) do not absorb water in the same way as monofilament. However, water can get into the rope, which is made of thousands of individual fibres. This occurs in a situation where the rope is "loose" - if it is taut, the wetting of the inside of the rope is negligible. The essential difference in favour of Mastrant type ropes is their mechanical properties and therefore their handling, ending, tensioning etc. It is therefore impossible to decide in general terms which solution is better for anchoring antennas. We recommend asking about the experience of users of our ropes in Italy.
