ant. duplexer and 2 ant. or ant. tuner?

[buckwhite]

hello all, i am green to all this ham stuff but i am ready to broaden my horizons. i have a question about setting up a new system in my car. i am looking seriously at the yaesu 7100M. i am curious about the dual band capability of this radio. i am pretty sure i will have to have 2 antennas or a tuning device of some sort. i would like opinions on this from folks that know a lot more than me on this subject. should i go with the 7100 or a strictly 2 meter radio like the 1500m? is there much activity on the 70cm band? you guys give me some input so i can have some more perspectives on this... thanks and L8ter

Well it really depends on the area, I know in ohio where i'm at the local ARC's (Amateur Radio Club's) reapeaters are on 70 cm and 2 m. The Rag chew repeater is the 70cm and the 2m tends to be more used for emergency comm. you should really check in your area and see if both are used or only one is used and that will end up giving you the solution to your dillemma. hope that helps!

"they use 2 meter and 70cm. the closest one is about 25 miles away ( repeater)"



You might be surprised at the number of repeaters available in your area.

You can program your scanner to listen to the local activity. Many antenna manufactures offer dual band antennas. Order some catalogs from HRO, AES, Universal Radio. These make great early morning reading material.

Duplexor or diplexor? Some people get all touchy about their definitions and probably change a little across different industries. If the radio you decide on getting has 2 different bands and a single antenna port, go with a dual band antenna. This is very common and by far the easiest. Not sure where you are at, but I would guess that most areas have 2 meter and 440 as the most popular bands for repeaters. They are usually salvaged business band repeaters that can be converted with very little effort.



The range of the repeater will vary on the location and installation. Just like a base station on 11 meters. Some are set up on mountain tops and can work over hundreds of miles. Some are on roof tops that handle a town. Some have satellite receivers that let 1 watt handhelds compete with the 100 watt mobiles. It’s all up to the guys running the repeaters.
