Bent radio AGN morphology depends on the density of the surrounding gas.However, bent sources are found inside and outside clusters, raising thequestion of how environment impacts bent AGN morphology. We analyze newLOw-Frequency Array Two-metre Sky Survey (LoTSS) Data Release II observationsof 20 bent AGNs in clusters and 15 not in clusters from the high-$z$ ClustersOccupied by Bent Radio AGN (COBRA) survey (0.35 $<$ $z$ $<$ 2.35). We measurethe impact of environment on size, lobe symmetry, and radio luminosity. We findthat the most asymmetric radio lobes lie outside of clusters and we uncover atentative correlation between the total projected physical area and clusteroverdensity. Additionally, we, for the first time, present spectral indexmeasurements of a large sample of high-$z$ bent sources using LoTSS and VeryLarge Array Faint Images of the Radio Sky at Twenty-centimeters (VLA FIRST)observations. We find that the median spectral index for the cluster sample is-0.76 $\pm$ 0.01, while the median spectral index for the non-cluster samplemedian is -0.81 $\pm$ 0.02. Furthermore, 13 of 20 cluster bent AGNs have flatcores ($\alpha$ $\geq$ -0.6) compared to 4 of 15 of non-clusters, indicating akey environmental signature. Beyond core spectral index, bent AGNs inside andoutside clusters are remarkably similar. We conclude that the non-clustersample may be more representative of bent AGNs at large offsets from thecluster center ($>$ 1.2Mpc) or bent AGNs in weaker groups rather than thefield.
