A handheld transceiver has very limited transmit power. Most of them use a different method of stating transmit power, stating peak envelope power rather than carrier power as used by panel mounted transmitters. That means there is approximately 1 watt of carrier for a hand-held rated at 5 watts – a substantial reduction in transmit range compared to your No. 1 com.
Even more telling is the hand-held antenna system efficiency compared to a real antenna mounted on…
