These connectors are no longer made and most dealers seem to be out of them. 
Here is one dealer that has four of them and is asking $1500/each 
http://antennasystems.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=L44P&Category_Code=LDF4con . 
If anyone does have any L44P or L44U connectors that they would like to get 
rid of for a more reasonable price, please send me a direct email

Assuming you're talking about Andrew LDF4, the Andrew part numbers are:

L44Z - splice
L44P - UHF male
L44U - UHF female

I'm not sure any of these are actually made anymore, but can be found in
stock at some dealers, and commonly at fleamarkets. Also RF Industries
(RFI) makes a UHF male for LDF4 if I'm not mistaken.
