Stealthy and versatile  Time owned: 0 to 3 months
I live in a small Apt at a large University and need to keep a low profile with my Amateur radio activities and yet would like to obtain reasonable performance despite my need to stay under the radar so to speak, Short story, The LNR Engineering EF-QUAD does not disappoint. Pruning and tuning can be a bit labor intensive though so please consider using an antenna analyzer when adjusting this antenna.

Excellent  Time owned: 0 to 3 months
I have had an EF-QUAD up for about three weeks. The high end is 60+ feet up and the low end 10'.
Bandwidth is very good and worst case VSWR was 1.45:1 ON 10M (RigExpert 600 vector analyzer).
Unlike any other end fed in the market place, this antenna uses a unique set of stubs allowing independent tuning of each band. No tuner required.

The matchbox does not use the generic electrical box, but rather a custom injection molded housing.

Multiband that works  Time owned: 0 to 3 months
I gave it a 5 as it arrived exactly as I'd expected based on other products from PAR and now LNR. Excellent package and build quality.

The antenna was installed in a hurry due to weather with one end at 28ft and the other about 20ft and tuning needs attention butat this low height I left it as was SWR for 40 was under 1.5, 20M under 1.5, 15M was under 1.7 and 10m under 2:1. Right now the antenna favors the CW ends of the bands. Those numbers for my radios are good enough as a right out of the box setup. The comparison antenna was the older PAR EF40,20,10 in all cases they were the same or the QUAD slightly better those being on 40M where the QUAD is full size and 15M where the triband is listen only. There was nothing really new save for 15M works well and 40M signal is better to known stations.
The plan is to raise it at the far end from 20ft to about 35-40ft and adjust the tuning.

On air it just works. It simplified my antenna system for the primary bands and is good for the nominal 100W level as well as qrp. In the past the QRP EF40/20/20 was my goto antenna this replaces it, a keeper. I'll keep the QRP tribander as well.

Over all:

Straight forward end fed four band antenna with good power capability and tuneable design. Its biggest feature is simple install where a center fed multiband would not be acceptable. The high build quality assures a long like in use.
