This is a very difficult question to answer, as there are a great many variables involved here. The frequency, height above ground of both the transmit and receive antenna, power output, any surrounding obstacles, sensitivity of the receiver and the type of the antenna - among many others - all play into answering this question.
A little pull up antenna probably will work OK on UHF frequencies and above, but start going lower in frequency and I would wager the efficiency would go downhill pretty fast. Given the addition of it being indoors and your received range gets decreased even further. In general - and there are some caveats that warrant a disucssion in another forum - an antenna nice and high, free of obstructions, will provide the best receiving range...best regards..Mike
