Αγαπητοί μου φίλοι σας εύχομαι καλή εβδομάδα.Η σημερινή ανάρτηση αφορά τα ομοαξονικά καλώδια μεταφοράς ραδιοσυχνότητας (RF). Για τα καλώδια δεν υπάρχει κάτι το συνταρακτικό να γράψει κάποιος, αφού οι πίνακες μιλούν από μόνοι τους.
Επέλεξα να αναρτήσω αυτό το πίνακα περισσότερο για να τον έχω κάπου αναρτημένο και να τον βρίσκω εύκολα όποτε τον χρειαστώ. Επιπλέον σκέφτηκα ότι για τον ίδιο λόγο ίσως και μερικοί από εσάς θα θέλατε να υπάρχει κάπου, προς άμεση αναζήτηση.
Ιδού λοιπόν ο πίνακας με τα τεχνικά χαρακτηριστικά των καλωδίων μεταφοράς ραδιοσυχνότητας.
Καλό ψάξιμο.
