REF: WAQP (DT), FCC Facility ID 67792 ERI Sales Order 36728
Dear Mr. Daly and Mr. Hart:
Electronics Research, Inc. (“ERI”) has been diligently working to fulfill the equipment
and services included on ERI Sales Order Number 36728, placed on your behalf by
DTVPros.
The cardioid azimuth pattern specified by WAQP’s FCC Construction Permit,
requires a large mast pipe (“outer conductor”) in order to achieve the customer
requested pattern without external pattern shapers (grids). The larger outer conductor
was chosen to avoid external pattern shapers outside of the radome which would
create icing and wind load problems. However, the larger outer also resulted in an
unwanted mode at the channel frequency (RF Channel 25) which wasn’t predicted by
design software or the original physical model testing. This mode issue was
discovered after the antenna was assembled for tuning.
Additional testing has indicated that sleeving the mast pipe (“outer conductor”) to
decrease the inside diameter and eliminate the mode conditions. The parts required
are currently being made for the inner sleeve and we anticipate returning to final
assembly within one week to 10 days. Without any further issues we should have a
finished and tested antenna by approximately August 1st,2019.
The Key activity dates for your order are:
