Just depends on your specific needs I guess. Both of your radios are dual band, but it looks like they (Smiley) only have 1 multi-band antenna on their site. It is telescoping so less durable. The antennas I have from them are all single-band. Given your specific use case, the RH77CA (I also have one and like it) or Signal Stick seem like probably a better choice to me (but I am far, far from being any kind of expert).
