The other radio will be a UHF D-STAR hotspot.

Tom-

What kind of range are you trying to achieve with the hotspot? The
little antenna that came with a UHF DVAP covers my property fairly well,
just sitting on a table.

I connected it to a Larsen dual-band mag-mounted antenna stuck on top of
a filing cabinet, and get about a half mile range when mobile. The DVAP
puts out about a tenth of a Watt. I suspect it can hear the 50 Watt
mobile a lot further away.

If you want range, consider taking the DVAP with you and connecting to
the internet through a cellular modem or telephone. I'm considering
getting a D-HAP, which holds everything but the radio and the cellular
connection. http://www.portableuniversalpower.com/dhap/
