Hello. I currently use a WSP255RS RCA 900Mhz transmitter

to send MP3s to a Sony Spiar Receiver.

The range of the RCA is 300'. I would like to know
if there is an easy way to slightly increase the range of transmission.


Is there a 900Mhz antenna amp or kit available to maximize range?

Would desoldering the flimpsy antenna and putting a thicker/longer
antenna increase range?

How about making a better antenna? Something like

Any ideas would be appreciated.
