Retro Telephone with External Antenna: Nokia 6310i Compatibility and GSM Signal Boost

Hello gentlemen ... I have been following the idea for a long time .. buying a retro phone with an external antenna .. preferably a long one .. whether it is permanent or detachable ..

I would use the phone in difficult conditions .. where my smartphone has no range.

Can an additional antenna be connected to Nokia 6310i? I saw that it has a socket on the back.



And the basic question ... does such an external antenna give a stronger GSM signal at all?

Maybe you have other suggestions for buying such a classic? Best regards.

In my opinion, adding an external antenna to the phone that you have with you all the time misses the point, you will not get a better range this way. The external antenna may be better, but you can lose all the gain from the external antenna on the cable. First, you need to check in the field in which you move most often which operator has the most relays and therefore has better coverage, ask people who live in the best network in the area, the Nokia 6310 is the most suitable phone for these purposes. If it is, of course, functional, because unfortunately one copy may differ significantly from the other. In any case, such things are organoleptically checked, a few phones and a few SIM cards from different operators.

Even a technically efficient old phone may not have modern bands (the GSM revolution started on one 900 MHz band, then the so-called DCS Idea Centertel 1800Mhz was humming in the metropolis, old phones in the centers had no coverage, then it flew).
A modern network uses many bands dynamically, in higher ones the attenuation of a thin cable is so great that it kills the antenna's effectiveness (more and more often marketing). The more bands there are, the more unlikely it is to make an effective antenna.
