I have three filters PAR FM / PAR 162/ and LTE filter. (I then go in to an EDA 8 way drop amp +4db) I just got the LTE today. After installing I'm happy to report things got better for me. (Your results may vary) I live near Las Vegas and there is a lot of RF in the area. Never thought LTE would be so noisy for my scanner setup. (DPD Log Periodic on the roof/100 ft belden 9913/ PAR VHF SYM 162/ PAR FM/ LTE/ EDA 8 way/ scanners) For $10 bucks worth a try. Not sure if it hurts my mil air band yet. Will find out monday when Nellis AFB starts flying. Just wanted to share the info. I hope somebody else tries the LTE in a city environment inline with the scanner and reports good or bad findings. I would suspect the thing that is happening here is the filters are lowering the noise floor for me and the scanners perform better?
